Primer for footwear constituting members, method for producing same, footwear constituting member, and footwear

摘要

The present invention provides a primer for footwear constituting members, wherein the primer includes an acid-modified polyolefin resin and a medium; the acid-modified polyolefin resin is a copolymer including an olefin unit and an unsaturated carboxylic acid unit; the copolymer includes as the olefin unit, a propylene unit (A) and an olefin unit (B) other than the propylene unit; the mass ratio (A/B) between the propylene unit (A) and the olefin unit (B) other than the propylene unit is 60/40 to 95/5; and the content of the unsaturated carboxylic acid unit is 0.1 to 10 parts by mass in relation to 100 parts by mass of the total amount of (A) and (B).

主权项

1. A primer for footwear constituting members comprising an acid-modified polyolefin resin and a medium,
wherein the acid-modified polyolefin resin is a copolymer including an olefin unit and an unsaturated carboxylic acid unit as copolymerization components; the copolymer includes as the olefin unit, a propylene unit (A) and an olefin unit (B) other than the propylene unit; a mass ratio (A/B) between the propylene unit (A) and the olefin unit (B) other than the propylene unit is 60/40 to 95/5; a content of the unsaturated carboxylic acid unit is 0.1 to 10 parts by mass in relation to 100 parts by mass of a total amount of the propylene unit (A) and the olefin unit (B) other than the propylene unit; and a content of a nonvolatile aqueous dispersing aid is 2% by mass or less in relation to the acid-modified polyolefin resin component.
