本发明是一种含有聚合物及溶剂的硬化性树脂组成物，所述聚合物具有下述式(1)所表示的结构单元、以及含羧基的结构单元。式(1)中，R 1 、R 2 及R 3 为氢原子或1价的烃基。R 4 为(a)(n+1)价的烃基、(b)在(a)烃基的碳-碳间含有选自由氧原子、硫原子、-SO-及-SO2-组成的群组中的至少1种的基、或(c)(a)烃基及(b)基所具有的氢原子的一部分或全部经选自由卤素原子、氰基、硝基、羧基、亚磺酸基、巯基及烷氧基组成的群组中的至少1种取代而成的基。R 5 为单键或-COO-*。;The invention provides a curable resin composition containing a polymer and a solvent, and the polymer has a structural unit represented by the following formula (1) and a structural unit containing a carboxyl group. In the formula (1), R 1 , R 2 and R 3 represent a hydrogen atom or a monovalent hydrocarbon group. R 4 represents (a) an (n+1) valent hydrocarbon group, (b) a group containing at least one selected from the group consisting of an oxygen atom, a sulfur atom, -SO- and -SO2- between carbon-carbon of the hydrocarbon group (a), or (c) a group formed by substituting a portion or all of hydrogen atoms owned by the hydrocarbon group (a) and the group (b) with at least one selected from the group consisting of a halogen atom, a cyano group, a nitro group, a carboxyl group, a sulfino group, a mercapto group and an alkoxy group. R 5 represents a single bond or -COO-*. |
