Abstract

Official abstract text for this publication.

A cationically polymerizable composition that provides a cured product and having an excellent balance of adhesion to various substrates, particularly, a silver substrate, and excellent handling properties. A cationically polymerizable composition including a double-decker type silsesquioxane compound having at least one alicyclic epoxy group in one molecule (A), a cationically polymerizable compound (B), a compound having a vinyl group and a cationically polymerizable cyclic ether (C), and a chelate-modified epoxy compound (D).

First claim

Opening claim text (preview).

What is claimed is: 1. A cationically polymerizable composition including a compound (A) represented by Formula (2), a cationically polymerizable compound (B), a compound (C) having a vinyl group and a cationically polymerizable cyclic ether, and a chelate-modified epoxy resin (D): wherein the compound (C) is a compound represented by Formula (4): the cationically polymerizable compound (B) contains a compound represented by Formula (B-1) and a compound represented by Formula (B-2), the chelate-modified epoxy resin (D) includes phosphate ester and is produced via reaction of a bisphenol A epoxy resin with phosphoric acid, and an amount of epoxy group/phosphate group is 28 to 33, an epoxy equivalent is 290 to 320 g/eq, and a phosphate equivalent is 8000 to 11000 g/eq, with respect to a total amount of (A) to (D), a content of the compound (A) represented by Formula (1) is 5 to 30 mass %, a content of the compound (C) having a vinyl group and a cyclic ether is 10 to 30 mass %, a content of the chelate-modified epoxy resin (D) is 10 to 50 mass %, and a content of the cationically polymerizable compound (B) is the remaining component ratio, a ratio between the content (mass %) of the compound represented by Formula (B-1) and the content (mass %) of the compound represented by Formula (B-2) is 5:1 to 2:1. 2. A laminate including a substrate and a cured film obtained by curing the cationically polymerizable composition according to claim 1 formed on the substrate. 3. The laminate according to claim 2 , wherein the substrate is one selected from the group consisting of a metal oxide, a metal substrate, and a plastic film.
