Abstract

PURPOSE: To obtain a varnish excellent in stability and properties of a cured product, etc., and suitable for use in photocurable prepreg tapes, by dissolving a base resin prepared by modifying an epoxy acrylate resin with a specified linear polymer in a volatile solvent.
CONSTITUTION: An epoxy resin is mixed with and allowed to act on 10W40phr polyvinyl formal or/and phenoxy resin at 150W230°C. Then, the titled varnish is obtained by mixing the product with a mixed solvent consisting of 80W60pts.wt. aromatic hydrocarbon and 20W40pts.wt. alcohol, and then further with 0.7W 1.2eq./eq. epoxy of (meth)acrylic acid, a small amount of a polymerization inhibitor (e.g., hydroquinone) and an epoxy ring-opening catalyst (e.g., benzylmethylamine), reacting the resulting mixture until an acid value of 10 or below is obtained and adding 0.05W5wt% photosensitizer (e.g., benzoin methyl ether).
