Abstract: The present invention provides a self-emulsification type emulsion exhibiting excellent adhesion to olefin-based base materials such as polyethylene and polypropylene without using an emulsifier. The self-emulsification type emulsion of the present invention comprises a tackifier and a modified polypropylene resin having an anionic functional group, and satisfies (1) and (2) given below:(1) the modified polypropylene resin having an anionic functional group is dispersed in water in the absence of an emulsifier, and (2) a dispersion particle comprising the modified polypropylene resin having an anionic functional group surrounds the tackifier.

Abstract: [Problem] The present invention aims to provide a high-molecular-weight modified copolymerized polyester resin that has a reactive functional group at a site other than the terminals of the molecular chain thereof, has an excellent reactivity with a curing agent (such as an epoxy resin or an isocyanate compound), and can be used to form an organic-solvent-and-emulsifier-free water dispersion having excellent storage stability.
[Solution] A modified copolymerized polyester resin (B) having a structure in which a copolymerized polyester resin (A) has an unsaturated polyvalent carboxylic acid added to a side chain thereof, and the copolymerized polyester resin (A) contains, as copolymerization components, at least one member selected from the group consisting of: a copolymerization component having an alicyclic structure (component x); a copolymerization component having six or more continuous methylene groups (component y); and an acyclic aliphatic copolymerization component having a tertiary carbon atom and a molecular weight of more than 100 (component z).

Abstract: The present invention provides a stable organic solvent solution-type adhesive composition that is in a solution state even at low temperatures and that has excellent adhesion to polyolefin base materials, in particular polyethylene substrates (both LDPE and HDPE). The invention provides an adhesive resin composition comprising a modified polyethylene copolymer (component A) having a melting point of less than 80° C., a terpene-based tackifier (component B), and an organic solvent (component C), wherein component B is contained in an amount of 30 to 100 parts by weight, per 100 parts by weight of component A.
