Coating material

摘要

There is provided a coating material comprising a mixture of a water-based resin composition of a thermoplastic elastomer (A) and/or a thermoplastic elastomer (B) in which at least one moiety is modified with a functional group; one of a water-based resin composition of a resin (G) formed from a copolymerizable monomer (G-1) which includes a monomer having an α,β-monoethylenic unsaturated group and other copolymerizable monomer, and a water-based resin composition of an urethane resin (U); and a water-based resin composition of a petroleum-based hydrocarbon resin (D) and/or a rosin-based resin (E) and/or a terpene-based resin (F). The coating material causing no separation phenomenon provides a coating composition or a primer with which spray coating is possible, and is a completely water-based coating material exhibiting an excellent adhesivity to a molded article of various resins such as polyolefin and a synthetic rubber or to metals such as a steel plate and aluminum.

a thermoplastic elastomer (A),
which may optionally be modified with functional groups, and comprises
a propylene-based elastomer (A-3) having a melting point measured by differential scanning calorimetry (DSC) of below 100° C. or no observed melting point,andan isotactic polypropylene (A-4) selected from
homopolypropylene having a copolymer component excluding propylene of 3 mol% or less,block polypropylene having a normal decane elution rubber component of 3 to 30 wt %,andrandom polypropylene having the melting point measured by DSC in the range of 110 to 150° C.; a water-based resin composition of an urethane resin (U); and a water-based resin composition of
a petroleum-based hydrocarbon resin (D) and/ora rosin-based resin (E)
selected from the group consisting of
natural rosins, polymerized rosins, modified rosins with maleic acid, fumaric acid or (metha)acryric acid, esterified products of rosins, phenol-modified products of rosins, esterified products of the phenol-modified products of rosinsandhydrogenated products thereofand/ora terpene-based resin (F).
