Two different origin of CTMP papers prepared from different individuals of Eucalyptus globulus trees showing high and low yellowing after photo-irradiation was compared before UV irradiation. As a result, Many polyphenol fragments derived from both liginin and extractives were observed as 30 peaks on the pyrogram. Among these peaks, Syringol 1+6, methylsyringol 3+11, methylguaiacol 4 and vinylsyringol 7+14 were recognized as major fragments relating to photo-yellowing level in over 5 pts difference of relative molar yields between two samples. G-lignin\\nfragment seems to enhance photo-yellowing although S-lignin fragment works vice versa. They can be used as indices for prediction of photo-yellowing level.", "subitem_description_type": "Abstract"}]}, "item_5_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "The Materials Research Society of Japan"}]}, "item_5_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "Copyright(C)2004 The Materials Research Society of Japan"}]}, "item_5_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AA10850652", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "13823469", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Seino, Teruyuki"}], "nameIdentifiers": [{"nameIdentifier": "38343", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yoshioka, Aki"}], "nameIdentifiers": [{"nameIdentifier": "38344", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Takai, Mitsuo"}], "nameIdentifiers": [{"nameIdentifier": "38345", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kojima, Yasuo"}], "nameIdentifiers": [{"nameIdentifier": "38346", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ishikura, Yukiko"}], "nameIdentifiers": [{"nameIdentifier": "38347", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ona, Toshihiro"}], "nameIdentifiers": [{"nameIdentifier": "38348", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ishida, Yasuyuki"}], "nameIdentifiers": [{"nameIdentifier": "38349", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ohtani, Hajime"}], "nameIdentifiers": [{"nameIdentifier": "38350", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-07-29"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "29(5)_2093-2096.pdf", "filesize": [{"value": "402.8 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 402800.0, "url": {"label": "29(5)_2093-2096.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/2649/files/29(5)_2093-2096.pdf"}, "version_id": "8fad6f47-06f8-4217-97f8-52b7b46d0b0f"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Pyrolysis-gas chromatography", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Mass spectrometry", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Tetrabutylammonium hydroxide", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Eucalyptus globulus", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Chemithermomechanical pulp", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Carbonyl group", "subitem_subject_scheme": "Other"}, {"subitem_subject": "photo-yellowing", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Characterization of Photo-Yellowing Trigger Compounds Repressing Paper Recyclability", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Characterization of Photo-Yellowing Trigger Compounds Repressing Paper Recyclability"}, {"subitem_title": "Characterization of Photo-Yellowing Trigger Compounds Repressing Paper Recyclability", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "487"], "permalink_uri": "http://hdl.handle.net/10191/33514", "pubdate": {"attribute_name": "公開日", "attribute_value": "2015-10-02"}, "publish_date": "2015-10-02", "publish_status": "0", "recid": "2649", "relation": {}, "relation_version_is_last": true, "title": ["Characterization of Photo-Yellowing Trigger Compounds Repressing Paper Recyclability"], "weko_shared_id": null}
