wherein X and Y, respectively, a divalent organic group represented by the following general formula (2) or (3)
wherein
wherein
(B) a crosslinking agent selected from formalin-modified or formalin-alcohol-modified amino condensates and phenolic compound having on average two or more methylol groups or alkoxymethylol groups in one molecule;
(C) a photoacid generator capable of generating an acid by decomposition with light having a wavelength of 190 to 500 nm; and
(D) a solvent.
