With a total of three patents to his name, Moriyama's work has implications in industries such as printing and coatings.

Latest Patents

Moriyama's latest patents include a crystalline polyester resin and a binder resin dispersion for toner. The crystalline polyester resin is obtained through condensation polymerization of a mixture that includes a polycarboxylic acid component and a polyol component. The specific ratio of carboxyl groups to hydroxyl groups is crucial, as it ranges from 100:108 to 100:120, with an acid value of 5 to 20 mgKOH/g. The polycarboxylic acid component features a C8-12 aliphatic dicarboxylic acid, while the polyol component includes a C8-12 aliphatic diol, ensuring that at least 90 mol % of the total carboxyl and hydroxyl groups come from these components. Additionally, he has developed a non-crystalline polyester resin, which is an amorphous polyester resin created through a reaction involving a polyester resin and a second poly-carboxylic acid component.
