らである。 The amount of piperidine compound added to the acrylic resin is 0.01 to 10 PHR. This is undesirable because if the amount of the piperidine compound is less than 0.01 PHR, the film formed on the surface of the holding bar will not have sufficient durability, and if the amount is 10 PHR or more, the amount of piperidine compound added will be less than 0.01 PHR. This is because it is undesirable because it blows out and stains the agricultural coating thin plate.
