Abstract
A precoated skin material for an automobile interior part comprising (a) a skin material for an automobile interior part and (b) a one-pack type thermally crosslinkable polymer composition comprising (i) a thermoplastic olefinic polymer having a carboxylic acid group or an acid anhydride group, (ii) a latent curing agent, (iii) a carbonyl compound as a solvent and (iv) a tackifier, which composition is coated on the back surface of the skin material, wherein the latent curing agent is a solid polyamine having a melting point of 80 to 200° C. which form hydrolyzable reaction products by a condensation reaction with the carbonyl compound used as the solvent, or a hydrolyzable reaction product of a diamine with a carbonyl compound.

A precoated skin material for an automobile interior part comprising (a) a skin material for an automobile interior part and (b) a one-pack type thermally crosslinkable polymer composition comprising (i) a thermoplastic olefinic polymer having a carboxylic acid group or an acid anhydride group, (ii) a latent curing agent, (iii) a carbonyl compound as a solvent and (iv) a tackifier, which composition is coated on the back surface of said skin material, wherein said latent curing agent is at least one compound selected from the group consisting of solid polyamines having a melting point of 80 to 200° C. which form hydrolyzable reaction products by a condensation reaction with said carbonyl compound used as the solvent, and hydrolyzable reaction products of diamines with carbonyl compounds.
An automobile interior part comprising a polyolefin substrate and a precoated skin material for an automobile interior part which is adhered to the surface of said polyolefin substrate, wherein said precoated skin material comprises (a) a skin material for an automobile interior part and (b) a one-pack type thermally crosslinkable polymer composition consisting essentially of (i) a thermoplastic olefinic polymer having a carboxylic acid group or an acid anhydride group, (ii) a latent curing agent, (iii) a carbonyl compound as a solvent and (iv) a tackifier, which composition is coated on the back surface of said skin material, wherein said latent curing agent is at least one compound selected from the group consisting of solid polyamines having a melting point of 80 to 200° C. which form hydrolyzable reaction products by a condensation reaction with said carbonyl compound used as the solvent, and hydrolyzable reaction products of diamines with carbonyl compounds.
