面台などに用いられている。Conventionally, gel coats have been used to enhance the decorativeness of molded products made of unsaturated polyester resin and glass fiber (hereinafter abbreviated as FRP) and artificial marble made of unsaturated polyester-like resin compositions and various fillers, and to provide protection, aesthetics, etc. It is widely used to improve Usually, a gel coat resin composition is coated on the surface of a mold to a thickness of about 0.1 to 0.5 aa and cured to obtain a gel coat, and then the above-mentioned FR
P or artificial marble is laminated or cast, and after hardening, the mold is removed to obtain a molded product. The molded products obtained in this way are used for large items such as ships and boats, for residential equipment such as bathtubs, bathroom units, and wall materials, and for kitchen equipment such as kitchen counters and washstands.

などの理由から広く利用されていないのが現状である。However, if these molded products lose their aesthetic appearance due to scratches or chips that occur during handling or use, their commercial value will be halved, so as a countermeasure, measures have been taken to increase the hardness of the gel coat surface. For example, molded products that require surface hardness are coated with acrylic, silicone, or other paints called hard coat agents and cured to improve scratch resistance. However, the hard coating agent must be cured by ultraviolet rays or electron beam curing, and the irradiation equipment for these active energy rays is expensive, and the hard coating agent is applied with a film thickness of 0.1 mm or less.
Currently, this method is not widely used because of the need to turn the entire workplace into a clean room due to the presence of foreign objects and dirt, and because it adds one additional work step.

硬度を犠牲にして実質的な大幅な硬度アップが図られて
いないのが現状である。Furthermore, as shown in Japanese Patent Application Laid-Open No. 63-108055, studies have been made to harden gel coat layers that combine unsaturated polyesters, styrene monomers, and polyfunctional acrylic compounds. However, although these methods can improve hardness, cracks occur due to the heating and cooling cycles that are essential for housing equipment and kitchen appliances and over time. The occurrence of cranks becomes a fatal defect in the above-mentioned molded products, and the commercial value is completely lost, so at present no efforts have been made to substantially increase the hardness at the cost of sacrificing hardness in order to prevent cranks.

る。The unsaturated group equivalent of the unsaturated polyester can be adjusted by adjusting the blending ratio of the materials used. The unsaturated group equivalent in the present invention is a value calculated from the charged molar composition of the acid component and alcohol component used in unsaturated polyester synthesis, and is calculated from the total weight of the charged acid component and alcohol component. The number of unsaturated groups contained in the unsaturated polyester (the number of unsaturated groups in the unsaturated polybasic acid used) is calculated based on the number of unsaturated groups contained in the unsaturated polyester (moles of the unsaturated polybasic acid used). number). This value is a model calculation value that ignores the dehydration reaction related to the acid component and alcohol component that are normally carried out in excess. For example, the unsaturated group equivalent of an unsaturated polyester obtained by reacting 1.0 mol of maleic anhydride and 1.10 mol of propylene glycol with a 0.1 mol excess of alcohol is ((98,1xl, O) + (76 ,1x1.10
