Abstract

Disclosed is an aqueous polyolefin resin dispersion including a polyolefin resin and an aqueous medium, wherein the polyolefin resin includes an olefin component and an unsaturated carboxylic acid component as copolymer components; the olefin component includes propylene (A) and an olefin(s) (B) other than propylene; the mass ratio (A/B) between the propylene (A) and the olefin(s) (B) other than propylene is 60/40 to 95/5; the content of the unsaturated carboxylic acid component as the copolymer component is 1 part by mass or more in relation to 100 parts by mass of the total mass of (A) and (B); and the content of the unsaturated carboxylic acid monomer in the dry residue of the aqueous dispersion is 10,000 ppm or less.

First claim

The invention claimed is:

1. An aqueous polyolefin resin dispersion comprising a polyolefin resin and an aqueous medium, wherein
the aqueous polyolefin resin dispersion does not include water-soluble polymers;
the polyolefin resin includes an olefin component and an unsaturated carboxylic acid component as copolymer components and is not bonded to water-soluble polymers;
the olefin component includes propylene (A) and an olefin(s) (B) other than propylene and does not include ethylene;
a mass ratio (A/B) between the propylene (A) and the olefin(s) (B) other than propylene is 60/40 to 95/5;
a content of the unsaturated carboxylic acid component as the copolymer component is 1 part by mass or more in relation to 100 parts by mass of a total mass of the propylene (A) and the olefin(s) (B) other than propylene; and
a content of an unsaturated carboxylic acid monomer in a dry residue of the aqueous dispersion is 10,000 ppm or less.

2. The aqueous polyolefin resin dispersion according to claim 1 , wherein the olefin(s) (B) other than propylene is butene.

3. The aqueous polyolefin resin dispersion according to claim 1 , further comprising a cross-linking agent and/or a polyurethane resin.

4. An aqueous dispersion-containing material selected from a coating agent, a primer, a coating material, an ink and an adhesive, wherein the aqueous dispersion-containing material includes the aqueous polyolefin resin dispersion according to claim 1 .

5. A coating film obtained from the aqueous polyolefin resin dispersion according to claim 1 .

6. The aqueous polyolefin resin dispersion according to claim 2 , further comprising a cross-linking agent and/or a polyurethane resin.

7. An aqueous dispersion-containing material selected from a coating agent, a primer, a coating material, an ink and an adhesive, wherein the aqueous dispersion-containing material includes the aqueous polyolefin resin dispersion according to claim 2 .

8. An aqueous dispersion-containing material selected from a coating agent, a primer, a coating material, an ink and an adhesive, wherein the aqueous dispersion-containing material includes the aqueous polyolefin resin dispersion according to claim 3 .

9. An aqueous dispersion-containing material selected from a coating agent, a primer, a coating material, an ink and an adhesive, wherein the aqueous dispersion-containing material includes the aqueous polyolefin resin dispersion according to claim 6 .

10. A coating film obtained from the aqueous polyolefin resin dispersion according to claim 2 .
