Title:
TRANSFER FILM, RESIN PATTERN FORMING METHOD USING TRANSFER FILM, AND CURED FILM PATTERN FORMING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/164016
Kind Code:
A1
Abstract:
The present invention provides: a photosensitive resin composition that is suitable for protection of a conductor part such as an electrode and that allows a transfer film to have satisfactory tack property, developability at low temperature, lamination property at low temperature, moisture permeability when in the form of a cured film, and adhesion to a conductor base material; a transfer film; and a production method therefor. The transfer film for forming a protective film for a conductor part comprises a support film and a photosensitive resin composition layer. The photosensitive resin composition layer includes (A) an alkali-soluble resin (excluding acid-modified epoxy (meth)acrylate compounds), (B) a compound containing a carboxyl group and an ethylenically unsaturated group, (C) a photopolymerizable compound, and (D) a photopolymerizable initiator. The alkali-soluble resin (A) has a weight-average molecular weight of 11,000-29,000 and an acid value not less than 100 mgKOH/g. The compound (B) has a weight-average molecular weight of 1,000-9,500, an acid value not less than 60 mgKOH/g, and a refractive index not less than 1.570. The ratio of the mass of the resin (A) to the mass of the compound (B) is 0.18-6.0.
