In such circuit boards, polyester film has a relatively low surface energy, and therefore has poor adhesion to printed circuit layers and transparent sheets for touch panels. Formation of an easily adhesive layer to improve the adhesive strength between the transparent sheet layer and the like has been carried out.

めたものである。Saturated polyester resin used in the present invention (component (a)
) is solvent soluble and dissolves in paints for easily adhesive compositions. Such solvent-soluble saturated polyester resins are known, for example, as disclosed in Japanese Patent Publication No. 51-102
As described in Publication No. 73, when producing a saturated polyester resin such as a polyethylene terephthalate resin, other acid components such as adipic acid or other aliphatic dibasic acids such as sebacic acid,
Aromatic dibasic acids such as isophthalic acid, orthophthalic acid, diphenyldicarboxylic acid, or other alcohol components, such as ■, 2-propylene glycol, 1,3-propylene glycol, 1°4-propylene glycol, 1,
It can be obtained by blending and reacting glycols such as 3-butanediol, diethylene glycol, and triethylene glycol. By blending such a third component, the crystallinity of the saturated polyester resin is reduced and the solubility of the saturated polyester resin in a solvent is increased.

:The weight ratio of component (c) is 100:10~30:5~
50 is preferred. When the amount of component (b) is more than the upper limit, the film becomes too hard and the adhesive strength is reduced, while when it is less than the lower limit, the curability tends to be poor. Component (c
) If the amount exceeds the upper limit, the blocking property of the coating increases, making it difficult to wind up the coated film, and if it decreases below the lower limit, the adhesive performance tends to be low, which is not preferable.

After annealing for 1 hour, a cross-cut test and a 180 degree peel test were conducted. For the eye test, for the normal test, ultraviolet resin ED450SS manufactured by Acheson was used with a thickness of approximately 20 mm.
The sample was coated on a micrometer and cured with ultraviolet rays. On the other hand, for the moisture resistance test, the same sample was left in an atmosphere of 60°C and 95% RH for 6 days. This was done by making a cut, then applying tape according to JISC5012, and then peeling off the tape.

Diabeam UR-6520 manufactured by Mitsubishi Rayon ■ was applied as an ultraviolet resin to the easily adhesive layer of the polyester film obtained in the Examples and Comparative Examples to a thickness of approximately 10 μm, and a polyester matte film was pasted on top of it. ,
The ultraviolet resin was cured by irradiation with ultraviolet light. When the polyester matte film was peeled off, a matte surface remained on the surface of the ultraviolet resin layer. The satin surface scratch strength test was conducted to judge whether the scratches are good or bad by scratching the satin surface with a fingernail.
