Abstract
本發明提供一種與塑膠基材之密合性優異之含有聚合物(A)之光硬化性樹脂組成物。
本發明係關於一種光硬化性樹脂組成物，其特徵在於含有使通式[I]所表示之化合物聚合而獲得之聚合物(A)(式中，R1表示[-CH2-CR3=CHR2]基、縮水甘油基、碳數1~5之烷基或氫原子，各個R1可不同，亦可相同，其中之至少1個為[-CH2-CR3=CHR2]基，[-CH2-CR3=CHR2]基中之R2及R3分別表示H或CH3)。
Description
本發明係關於一種含有使通式[I]所表示之化合物聚合而獲得之聚合物(A)之光硬化性樹脂組成物、以及含有該樹脂組成物而成之墨水、塗料。更詳細而言，本發明係關於一種與塑膠基材之密合性優異之光硬化性樹脂組成物。
習知，藉由光(例如紫外線)而硬化之各種樹脂組成物被用於墨水、塗料、接著劑、光阻劑等。例如，紫外線硬化型之印刷墨水其硬化速度快而可於短時間內硬化；由於未使用溶劑而適合環境；及節省資源、節能等方面上評價較高而被廣泛實用化。
此種樹脂組成物之中，含有自苯二甲酸二烯丙酯(鄰苯二甲酸二烯丙酯、間苯二甲酸二烯丙酯、對苯二甲酸二烯丙酯)衍生之苯二甲酸二烯丙酯樹脂之樹脂組成物被採用作紙用之UV膠版墨水。
然而，已知於用作膠版墨水時若摻合苯二甲酸二烯丙酯樹脂，則與塑膠基材之密合性不足(例如，專利文獻1)。又，記載有含有顏料、紫外線硬化性樹脂、及光聚合起始劑之非吸收材料用紫外線硬化型噴墨墨水組成物，且紫外線硬化性樹脂中為具有三環之3官能以上之烯丙
基、丙烯酸聚酯及(甲基)丙烯酸酯者(專利文獻2)。然而，上述非吸收材料用紫外線硬化型噴墨墨水組成物係噴墨用之組成物，於對塑膠基材之密合性或乾燥性之方面上並不充分。
近年來，市售有聚對苯二甲酸乙二酯(PET)、聚丙烯(PP)等各種各樣之塑膠製品，而要求提高苯二甲酸二烯丙酯樹脂之作為缺點之與塑膠基材之密合性。

本發明之目的在於提供一種與塑膠基材之密合性優異之含有聚合物(A)之光硬化性樹脂組成物。
本發明者進行了努力研究，結果發現，含有使具有特定結構之化合物聚合而獲得之聚合物(A)之光硬化性樹脂組成物與塑膠基材之密合性優異，從而思及本發明。
即，本發明之光硬化性樹脂組成物其特徵在於：
含有使下述通式[I]所表示之化合物聚合而獲得之聚合物(A)。
(式中，R1表示[-CH2-CR3=CHR2]基、縮水甘油基、碳數1~5之烷基或氫原子，各個R1可不同，亦可相同，其中之至少1個為[-CH2-CR3=CHR2]基，[-CH2-CR3=CHR2]基中之R2及R3分別表示H或CH3)。
若含有使上述通式[I]所表示之化合物聚合而獲得之聚合物(A)，則成為對塑膠基材之密合性優異且乾燥性亦優異之光硬化性樹脂組成物。
又，該光硬化性樹脂組成物對PP(聚丙烯)樹脂之密合性尤其優異，故而作為習知之使用苯二甲酸二烯丙酯樹脂之組成物難以提高密合性之PP樹脂用之墨水、塗料之成分適合。
本發明之光硬化性樹脂組成物較佳為進而含有乙烯性不飽和化合物(B)。藉由使用乙烯性不飽和化合物，光硬化性樹脂組成物之乾燥性提高，而可調整為適合用於印刷之黏度，而成為塗佈作業性優異之組成物。
本發明之光硬化性樹脂組成物較佳為進而含有光聚合起始劑。藉由含有光聚合起始劑，藉由光照射而進行之聚合順利地進行，故而可於短時間內獲得硬化物。
本發明之墨水其特徵在於含有本發明之光硬化性樹脂組成物。
該墨水適合作為用以印刷於塑膠基材之墨水，尤其是適合作為用以印刷於PP樹脂製之片材、膜等基材之墨水。
本發明之塗料其特徵在於含有本發明之光硬化性樹脂組成物。該塗料適合作為用以繪製於塑膠基材之塗料，尤其是適合作為用以繪製於PP樹脂製之片材、膜等基材之塗料。
又，本發明之塗料較佳為套印(overprinting)清漆。
根據本發明，於用作墨水、塗料、接著劑及光阻劑之成分之情形時，獲得對合成高分子之基材、尤其是塑膠基材之密合性優異之光硬化性樹脂組成物。
