Document Type and Number:
WIPO Patent Application WO/2024/034384
Kind Code:
A1
Abstract:
[Problem] The present invention addresses the problem of providing: a curing-reactive organopolysiloxane which has good alkali solubility; and a high energy ray-curable composition which contains this curing-reactive organopolysiloxane. [Solution] The present invention provides: a co-modified branched organopolysiloxane which is represented by average unit formula (1) (A3SiO1/2)a(A2SiO2/2)b(RSiO3/2)c(SiO4/2)d (wherein R represents a monovalent hydrocarbon group or the like; each A represents a group that is selected from among a similar group as R, a specific phenolic hydroxyl group-containing organic group M1 and a specific carboxylic acid-containing organic group M2; at least one A is M1; at least one A is M2; and a, b, c and d satisfy the following conditions 0 ≤ a, 0 ≤ b, 0 < (a + b) and 0 < (c + d)); and a use of this co-modified branched organopolysiloxane.
