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

The invention claimed is:

1. 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 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.

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), and an isocyanate group-containing (meth)acrylate compound (E) as 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. The (meth)acryloyl group-containing acrylic-modified alkyd resin according to claim 1 , wherein the acrylic resin intermediate (A) has an oil length of 10 or more.

4. The (meth)acryloyl group-containing acrylic-modified alkyd resin according to claim 1 , wherein the alkyd resin intermediate (B) has an oil length of 10 or more and a weight average molecular weight (Mw) in the range of 1,000 to 100,0000.

5. The (meth)acryloyl group-containing acrylic-modified alkyd resin according to claim 1 , wherein the polyisocyanate compound (C) is a polyisocyanate compound having a ring structure in the molecular structure.

6. An active-energy-ray-curable resin composition comprising the (meth)acryloyl group-containing acrylic-modified alkyd resin according to claim 1 .

7. An undercoat agent for an inorganic-material thin film, comprising the active-energy-ray-curable resin composition according to claim 6 .

8. A coating film comprising a product made from the undercoat agent according to claim 7 .

9. A molded body comprising an undercoat layer made from the undercoat agent according to claim 7 .

10. The (meth)acryloyl group-containing acrylic-modified alkyd resin according to claim 2 , wherein the acrylic resin intermediate (A) has an oil length of 10 or more.

11. The (meth)acryloyl group-containing acrylic-modified alkyd resin according to claim 2 , wherein the alkyd resin intermediate (B) has an oil length of 10 or more and a weight average molecular weight (Mw) in the range of 1,000 to 100,0000.

12. An active-energy-ray-curable resin composition comprising the (meth)acryloyl group-containing acrylic-modified alkyd resin according to claim 2 .

13. An undercoat agent for an inorganic-material thin film, comprising the active-energy-ray-curable resin composition according to claim 12 .

14. A coating film comprising a product made from the undercoat agent according to claim 13 .

15. A molded body comprising an undercoat layer made from the undercoat agent according to claim 13 .
