Abstract:
1. A solvent dispersion of a composite resin, which comprises a solvent and a composite resin comprising a thermoplastic elastomer (A) and a polymer of copolymerizable monomers (B) comprising a monomer having an α,β-monoethylenically unsaturated group and other copolymerizable monomer(s), wherein the thermoplastic elastomer (A) is a propylene-based elastomer having a molecular weight distribution (Mw/Mn) of 3 or less as measured by gel permeation chromatography (GPC), and the copolymerizable monomers (B) include at least one monomer containing no functional groups, wherein the thermoplastic elastomer (A) is obtained by copolymerizing propylene and β-olefin, or by copolymerizing propylene, α-olefin and ethylene, in the presence of a catalyst for olefin polymerization which contains: [i] a transition metal compound represented by the following formula (1): wherein M is a transition metal atom from Groups IVb, Vb and VIb of the Periodic Table of Elements; R 1 , R 2 , R 3 and R 4 are each a hydrogen atom, a halogen atom, a hydrocarbon group having 1 to 20 carbon atoms, a halogenated hydrocarbon group having 1 to 20 carbon atoms, a silicon-containing group, an oxygen-containing group, a sulfur-containing group, a nitrogen-containing group or a phosphorus-containing group, and some of the adjacent groups may be bonded to each other, and form a ring together with the carbon atom to which these groups are attached; X 1 and X 2 may be identical with or different from each other, and are each a hydrogen atom, a halogen atom, a hydrocarbon group having 1 to 20 carbon atoms, a halogenated hydrocarbon group having 1 to 20 carbon atoms, a silicon-containing group, an oxygen-containing group or a sulfur-containing group; and Y is a divalent hydrocarbon group having 1 to 20 carbon atoms, a divalent halogenated hydrocarbon group having 1 to 20 carbon atoms, a divalent silicon-containing group, a divalent germanium-containing group, a divalent tin-containing group, —O—, —CO—, —S—, —SO—, —SO 2 —, —NR 5 —, —P(R 5 )—, —P(O)(R 5 )—, —BR 5 — or —AlR 5 —, wherein R 5 is a hydrogen atom, a halogen atom, a hydrocarbon group having 1 to 20 carbon atoms or a halogenated hydrocarbon group having 1 to 20 carbon atoms, and [ii] at least one compound selected from the group consisting of:
