Abstract
A novel imide silicone resin is provided that on heat treatment is capable of easily forming a cured resin coating with excellent solvent resistance, humidity resistance and durability, as well as a production process therefor. The imide silicone resin has a structure of the formula (1) shown below, which is the addition reaction product of an organopolysiloxane with two silicon-bonded hydrogen atoms, and an imide compound with two olefin-based carbon-carbon double bonds
Claims16
An imide silicone resin with a structure represented by a general formula (1) shown below:
- wherein, each A is a bivalent organic group, each B represents, independently, a trivalent group selected from groups having the formulas shown below, in which two single bonds protruding in a substantially identical direction are bonded to an imide ring to form a ring structure and the third single bond is bonded to Y, Y is a bivalent group represented by formula (2) shown below, and n is an integer from 2 to 100:
- wherein in each formula, X represents a hydrogen atom or a methyl group,
- wherein, R1 represents, independently, a monovalent organic group, and m is an integer from 0 to 100.
