Abstract

Provided is a resin composition having a large proportion of polyolefin components, allowing preparation of a solution having a high solid content, having a good solution property after long-term storage, having good pigment dispersibility, and including a modified product of component (A): polyolefin resin with component (B): (meth)acrylic acid and/or (meth)acrylic acid ester, in which the weight ratio of the component (A) to the component (B) ((A)/(B)) is 90/10 to 30/70, and the component (B) contains 20% by weight or more of component (B1): an alkoxy (poly)alkylene glycol mono(meth)acrylic acid ester.

First claim

The invention claimed is:

1. A resin composition, comprising:
a modified product of component (A): acid-modified polyolefin resin with component (B): (meth)acrylic acid and/or (meth)acrylic acid ester,

wherein the component (B) comprises 20% by weight or more of an (poly)alkylene oxide glycol mono(meth)acrylic acid ester (B1) of formula (I):
CH 2 ═C(R 1 )COO—(CH 2 —CH 2 —O—) n —R 2   (I),

wherein
R 1 is H or a methyl group,
R 2 is an alkyl group having 1 to 2 carbon atoms, and
n is 1.

2. The resin composition of claim 1 , having a weight average molecular weight in a range of from 10,000 to 200,000.

3. The resin composition of claim 1 , wherein the component (B) further comprises a (meth)acrylic acid or (meth)acrylic acid ester other than the (poly)alkylene oxide glycol mono(meth)acrylic acid ester (B1).

4. The resin composition of claim 1 , wherein the component (A) is an acid-modified chlorinated polyolefin resin.

5. The resin composition of claim 1 , further comprising:
an organic solvent.

6. A primer coating material, comprising:

12. The resin composition of claim 1 , wherein the acid-modified polyolefin resin that is graft-modified with an α,β-unsaturated carboxylic acid, and
wherein the α,β-unsaturated carboxylic acid comprises maleic anhydride.

13. The resin composition of claim 1 , wherein the component (A) comprises an acid-modified chlorinated polyolefin resin, and
wherein a chlorine content of the acid-modified chlorinated polyolefin resin is in a range of from 10 to 40 wt., measured based on JIS-K7229:1995.

14. The resin composition of claim 1 , wherein the component (A) comprises an acid-modified chlorinated polyolefin resin, and
wherein a chlorine content of the acid-modified chlorinated polyolefin resin is in a range of from 15 to 30 wt. %, measured based on J1S-K7229:1995.

15. The resin composition of claim 1 , wherein the acid-modified polyolefin resin is grafted and has a graft weight in a range of from 2 to 20 wt. %, measured in accordance with JIS K 0070:1992.

16. The resin composition of claim 1 , wherein the acid-modified polyolefin resin has a propylene constituent unit content of 60 wt.

17. A resin composition, comprising:
a modified product of component (A): chlorinated polyolefin resin or acid-modified chlorinated polyolefin resin with component (B): (meth)acrylic acid and/or (meth)acrylic acid ester, wherein
wherein an (A)/(B) weight ratio of the component (A) to the component (B) is in a range of from 90/10 to 30/70, and
wherein the component (B) comprises 20% by weight or more of an (poly)alkylene oxide glycol mono(meth)acrylic acid ester (B1) of formula (I):
CH 2 ═C(R 1 )COO—(CH 2 —CH 2 —O—) n —R 2   (I),

wherein
R 1 is H or a methyl group,
R 2 is an alkyl group having 1 or 2 carbon atoms, and
n is 1.

18. The resin composition of claim 17 , wherein the component (A) is a chlorinated polyolefin resin.

19. The resin composition of claim 17 , wherein the component (A) is an acid-modified chlorinated polyolefin resin.

20. The resin composition of claim 17 , wherein a chlorine content of the chlorinated polyolefin resin or the acid-modified chlorinated polyolefin resin is in a range of from 10 to 40 wt., measured based on JIS-K7229:1995.
