Patent ID: 7462436

Claim:
A coated substrate comprising a substrate and a photosensitive layer, said photosensitive layer being at least 3 μm in thickness and comprising: (A) an alkali-soluble novolak resin having a weight average molecular weight of 1,000 to 50,000, in which a portion of hydrogen atoms of phenolic hydroxyl groups are substituted with 1,2-naphthoquinonediazidesulfonyl groups; and (B) a dissolution promoter comprising at least one compound selected from a group consisting of compounds represented by a general formula (b-1) and a general formula (b-11) shown below; wherein, R 1 to R 9 each represent, independently, a hydrogen atom, an alkyl group, a halogen atom, or a hydroxyl group, although at least one of R 1 to R 9 represents a hydroxyl group; and R 10 to R 15 each represent, independently, a hydrogen atom, an alkyl group, an alkenyl group, a cycloalkyl group or an aryl group; wherein, R 41 to R 43 each represent, independently, a lower alkyl group, a cycloalkyl group or a lower alkoxy group; p and q each represent an integer from 1 to 3; and r, s and t each represent either 0, or an integer from 1 to 3.
