The present invention aims to provide a copolymerized polyester and a resin composition which are excellent in storage stability, water-resistant adhesion, processability, weathering resistance and leveling property. According to the present invention, there is provided a copolymerized polyester containing a polyvalent carboxylic acid component and a polyhydric alcohol component as copolymerization components, wherein, when a content of the polyvalent carboxylic acid component is taken as 100% by mole, a content of an alicyclic polyvalent carboxylic acid component is 50% by mole or more, and wherein the copolymerized polyester has an acid value of 170 to 1000 equivalents/10g.

Copolymerized polyester and water dispersion

The present invention aims to provide an adhesive composition which exhibits high adhesive property not only to the conventional polyimide and polyester film but also to a metal substrate, can achieve high solder heat resistance and exhibits excellent low-dielectric characteristics. According to the present invention, there is provided an adhesive composition containing an acid-modified polyolefin (a), an oligo-phenylene ether (b) having a number-average molecular weight of 3000 or less, and an epoxy resin (c), wherein the adhesive composition satisfies the following requirement(s) (A) and/or (B):

Low-dielectric adhesive composition

The present invention aims to provide an adhesive composition having excellent adhesive property and excellent anti-fogging property by way of simple and easy means such as co-extrusion with a substrate film, extrusion coating, solvent coating, etc. According to the present invention, there is provided an adhesive composition, characterized in that it contains a polyester resin (A) and an anti-fogging agent (C), and satisfies the following requirement (1):

Adhesive composition having anti-fogging property
