Abstract
The invention provides a crystalline polyester resin obtained by condensation polymerization of a mixture comprising a polycarboxylic acid component and a polyol component, present in a range such that the ratio of the number of carboxyl groups from the polycarboxylic acid component and the number of hydroxyl groups from the polyol component is in the range of 100:108 to 100:120, and having an acid value of 5 to 20 mgKOH/g, wherein the polycarboxylic acid component includes a C8-12 aliphatic dicarboxylic acid, the content ratio of carboxyl groups from the C8-12 aliphatic dicarboxylic acid is at least 90 mol % of the total amount of carboxyl groups from the polycarboxylic acid component, the polyol component includes a C8-12 aliphatic diol, and the content ratio of hydroxyl groups from the C8-12 aliphatic diol is at least 90 mol % of the total amount of hydroxyl groups from the polyol component.
