After dissolving in a tank with a high-speed stirrer with a solvent consisting of 20 parts of cellosolve acetate, 10 parts of cellosolve acetate, and 10 parts of butyl cellosolve, the crosslinking resin was prepared using mithylated melamine resin Cymel 370 (nonvolatile content 88%) manufactured by Mitsui Toatsu Chemical Co., Ltd.6. Butylated urea resin P-138-60 (nonvolatile content 60%) manufactured by Dainippon Ink and Chemicals Co., Ltd. 12
A transparent coating material was prepared by adding 50% of the total amount of the solution in a tank equipped with a high-speed stirrer and stirring and mixing. The white paint described in Example 1 was applied to a stain-free steel high top (0.24 mm thick) manufactured by Toyo Kohan Co., Ltd. using a natural roller coater method at a rate of 120±10 mg.
100cm2 was coated and dried in a hot air continuous drying oven at 190℃ for 10 minutes. Furthermore, 60±5 mg/g of the transparent paint described in Example 2 or Example 3 was applied to this painted surface using the same natural roller coater method as a gloss varnish.
100cm2 was coated and dried in a hot air continuous drying oven at 170℃ for 10 minutes. The first plate is made using a body plate with the painted surface as the outer surface.
When a film cartridge as shown in the figure was prepared, improved performance as shown in Table 1 was confirmed. The white paint described in Comparative Example 1 was applied to a stain-free steel high top (0.24 mm thick) manufactured by Toyo Kohan Co., Ltd. using a natural roller coater method at a rate of 120 ± 10 mg/
Paint at a rate of 100cm2 and dry in a hot air continuous drying oven at a rate of 190cm2.
Dry for 10 minutes at °C. Furthermore, the transparent paint described in Comparative Example 2 or Comparative Example 3 was applied as a gloss varnish to this painted surface at a rate of 60 ± 5 mg/100 cm 2 using the same natural roller coater method, and then dried at 170°C for 10 days in a hot air continuous drying oven. Dry for a minute. When a film cassette as shown in Figure 1 was prepared using a body plate with the painted surface on the outside, it had the characteristics of the "low-molecular polyester, amino resin paint" shown in Table 1. It was confirmed that the mechanical strength was clearly inferior to that of a paint made of molecular weight oil-free polyester and amino resin.
