Embodiment

[0087] (1) Preparation of samples A to G

[0088] Each of Samples A to G comprising an aqueous dispersion of a saturated polyester resin was prepared as follows:

[0089] A reaction vessel having a volume of 1000 ml equipped with a stirrer, a nitrogen gas introduction port, a thermometer, a fractionator column, and a cooling condenser was prepared. Components other than trimellitic anhydride listed as "Components of Saturated Polyester Resin" in Tables 1 and 2 were added to a reaction vessel to obtain a mixture. The mixture was heated to 200°C under nitrogen atmosphere and atmospheric pressure while stirring and mixing, and then further gradually raised to 250°C over 4 hours to complete esterification and transesterification. Next, trimellitic anhydride listed as "Constituents of Saturated Polyester Resin" in Tables 1 and 2 was added to the mixture. After gradually reducing the pressure to 0.67 hPa (0.5 mmHg) at 230° C., the mixture was held for 2 hours to conduct a polycond...

Abstract

The present invention provides a primer composition which can be applied onto a substrate to form a primer layer having good adhesiveness and high transparency. The primer composition includes a polymerization reaction product (A); maleic acid modified polyolefin resin (B) and water (C). The polymerization reaction product (A) is a product produced by emulsion polymerization of an olefinic bond unsaturated monomer (b) in a mixture comprising saturated polyester resin (a) and the olefinic bond unsaturated monomer (b). The acid value of the saturated polyester resin (a) is 10 mg KOH / g to 100 mgKOH / g. The olefinic bond unsaturated monomer (b) comprises a nonionic olefinic bond unsaturated monomer (b1).

Description

technical field [0001] The present invention relates to a primer composition, a laminate and a method for producing the primer composition, and in particular to a primer composition for forming a primer layer, including a primer composition formed from the primer composition. The laminate of the primer layer, and the method for producing the primer composition. Background technique [0002] On various substrates such as films made of polyolefin resins such as polypropylene or polyethylene, coatings may be formed, inks may be provided for printing, or metal deposition layers may be formed to provide gas barrier properties. For example, when the substrate has no polar groups, the substrate may be subjected to surface treatment such as corona discharge, plasma treatment, Frame treatment, UV irradiation treatment and solvent treatment. [0003] However, there is a problem that these surface treatments involve handling with attendant danger. In addition, there is a problem tha...
