Abstract
A polyurethane resin is synthesized from a compound represented by the following Formula (1), a polymerizable composition includes the polyurethane resin, a planographic printing plate precursor includes a photosensitive layer including the composition, and a method produces a diol compound that can be used as a raw material of the polyurethane resin. In Formula (1), R1 and R2 each independently represent a single bond or an alkylene group optionally having a substituent, R3 represents a hydrogen atom or an alkyl group, R4 represents a hydrogen atom or an alkyl group, and A represents a divalent or higher linking group, provided that R1 and R2 are not both a single bond.
Claims11

- wherein, in Formula (1), each of R1 and R2 independently represents a single bond or an alkylene group optionally having a substituent, R3 represents a hydrogen atom or an alkyl group, R4 represents a hydrogen atom or an alkyl group, and A represents a divalent or higher linking group that comprises no cyclic structure in a part of its structure, provided that R1 and R2 are not both a single bond.
An alkali-soluble polyurethane resin synthesized from a compound represented by the following Formula (1):
- wherein, in Formula (1), each of R1 and R2 independently represents a single bond or an alkylene group optionally having a substituent, R3 represents a hydrogen atom or an alkyl group, R4 represents a hydrogen atom or an alkyl group, and A represents a divalent or higher linking group that comprises no cyclic structure in a part of its structure, provided that R1 and R2 are not both a single bond.
A method for producing a compound represented by Formula (2), the method comprising hydrolyzing a compound represented by the following Formula (3) with water at a reaction temperature of 60° C. or lower without using an acidic catalyst:
- wherein, in the Formula (2), R3 represents a hydrogen atom or an alkyl group, R4 represents a hydrogen atom or an alkyl group, and A represents a divalent or higher linking group and, in the Formula (3), each of R5 and R6 independently represents a hydrogen atom or an alkyl group, and R3, R4 and A are as for the same as R3, R4 and A in the Formula (2).
