Abstract

Provided are a resin material that is superior in coating appearance and adhesion to substrates and can be used not only under organic solvent-diluted conditions but also under aqueous solvent-diluted conditions; an undercoat agent for an inorganic-material thin film containing the same; and a molded body produced by using the undercoat agent for an inorganic-material thin film. Provided are a (meth)acryloyl group-containing acrylic-modified alkyd resin, an active-energy-ray-curable resin composition containing the same, the undercoat agent for an inorganic-material thin film, and a molded body produced by using the undercoat agent for an inorganic-material thin film.

First claim

2 . A (meth)acryloyl group-containing acrylic-modified alkyd resin, which comprises a reaction product of an acrylic resin intermediate (A), an alkyd resin intermediate (B), a polyisocyanate compound (C), and a hydroxy group-containing (meth)acrylate compound (D) as essential starting materials;
wherein the acrylic resin intermediate (A) has an acid value in the range of 50 to 300 mg KOH/g and a weight average molecular weight (Mw) in the range of 1,000 to 50,000.

3 . A (meth)acryloyl group-containing acrylic-modified alkyd resin, which comprises a reaction product of an acrylic resin intermediate (A), an alkyd resin intermediate (B), and an isocyanate group-containing (meth)acrylate compound (E) as essential starting materials;
wherein the acrylic resin intermediate (A) has an acid value in the range of 50 to 300 mg KOH/g and a weight average molecular weight (Mw) in the range of 1,000 to 50,000.

4 . (canceled)
