Document Type and Number:
WIPO Patent Application WO/2024/034383
Kind Code:
A1
Abstract:
[Problem] To provide: a curable reactive organopolysiloxane having good alkali solubility; and a high energy ray-curable composition containing the same. [Solution] Provided is a phenolic hydroxyl group-containing branched organopolysiloxane represented by average unit formula (1); and use thereof. Formula (1): (A3SiＯ1/2)a(A2SiO2/2)b(RSiO3/2)c(SiO4/2)d. In the formula, R is a monovalent hydrocarbon group or the like, A is a group selected from among a similar group to R and a group M1 or the like, which is represented by formula (21) (in the formula, R1 is a divalent hydrocarbon group having 2 to 6 carbon atoms, X is a hydroxyl group, Z is a monovalent group represented by -OR3 (in the formula, R3 is an acid-dissociable group), m1 is a number within the range 1-3, and k is a number within the range 0-3), at least one A is M1, and a, b, c and d satisfy the conditions: 0 ≤ a, 0 ≤ b, 0 < (a+b), and 0 < (c+d).
