This invention relates to a photosenstive composition characterized by comprising components A, B and C, and a photosensitive film and a stencil for screen printing using the photosensitive composition; Component A: a poly(vinyl alcohol) polymer represented by formula (1) or (2)
wherein R1 represents a hydrogen atom, an alkyl or aralkyl group having 1 to 10 carbon atoms, wherein the alkyl and aralkyl groups may be substituted by a hydroxyl or carbamoyl group and the bond between carbon atoms thereof may be present through an oxygen atom or an unsaturated bond; R2 represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms; m is an integer of 1 to 6; n is 0 or 1; and X- represents a halogen ion, a phosphate ion, a methosulfate ion, or a sulfonate ion, or a mixture of the anions; component B: a radical polymerizable monomer containing at least one ethylenically unsaturated bond and possesses an anion dissociating capability; and component C: a radical photoinitiator. According to the present invention, there are provided a photosensitive resin composition having excellent long-term storage stability, which is of one-pack type and is developable with neutral water, a photosensitive film, and a stencil for screen printing.
本发明涉及一种感光组合物,其特征是由 A、B 和 C 三种组分以及感光胶片和使用该感光组合物进行丝网印刷的网版组成; A组分:由式(1)或(2)表示的聚乙烯醇聚合物; B组分:由式(1)或(2)表示的聚乙烯醇聚合物; C组分:由式(1)或(2)表示的聚乙烯醇聚合物; D组分:由式(1)或(2)表示的聚乙烯醇聚合物。
其中 R1 代表氢原子、具有 1 至 10 个碳原子的烷基或芳烷基,其中烷基和芳烷基可被羟基或氨基甲酰基取代,其碳原子之间的键可通过氧原子或不饱和键存在;R2 代表氢原子或具有 1 至 3 个碳原子的烷基; m 是 1 至 6 的整数; n 是 0 或 1; X- 代表卤素离子、磷酸根离子、甲硫酸根离子或磺酸根离子,或这些阴离子的混合物; B 组分:含有至少一个乙烯不饱和键并具有阴离子离解能力的自由基可聚合单体;以及 成分 C:自由基光引发剂。根据本发明,提供了一种具有出色的长期储存稳定性的感光树脂组合物,该组合物为单组分类型,可使用中性水显影,还提供了感光胶片和丝网印刷用网版。
