(A) + (B) + (C)] is an unsaturated polyester resin composition characterized by containing 40 to 60% by weight.

硬化性が悪くなり好ましくない。The tall oil fatty acid used in the present invention has relatively few double bonds and is usually referred to as a semi-drying oil. Soybean oil fatty acids have a large change in hardness over time, which is undesirable.
In the case of coconut oil fatty acids, tall oil fatty acids, which are undesirable because they cannot remove the tackiness of the surface of the cured product, are used to partially replace the aforementioned unsaturated polybasic acids. In this case, the blending ratio of tall oil fatty acid is preferably 15 to 30 equivalent% based on the total unsaturated polybasic acid. If the blending ratio is less than 15% by weight, the curability is poor;
Moreover, if it exceeds 30 equivalent %, the hardness of the cured product increases and the flexibility decreases, which is undesirable.
C)] is preferably 40 to 60% by weight. If the amount is less than 40% by weight, the initial hardness will be large and flexibility will be poor, which is undesirable. If it exceeds 60% by weight, the curability will deteriorate and it is not desirable. do not have.
