A polyester resin that is a condensation polymer of a polyol mixture including an epoxidized vegetable oil and a rosin additive, a polycarboxylic acid and a vegetable-derived polyol; has a mass ratio (rosin/epoxidized vegetable oil) between the rosin and the epoxidized vegetable oil of 2-10; and has a biomass content of at least 80%. The polyester resin has a high proportion of biomass-derived components and can be used to obtain an offset printing ink composition that has excellent scratch resistance and excellent abrasion resistance.

Described herein are methods, and compositions for use in the coloration of materials. The compositions described herein are black pigments derived primarily from recently-living plants or animals and are therefore renewable.

A liquid ejecting apparatus, a liquid ejecting method and an ink are provided, so as to appropriately increase the strength of ink after fixing. The liquid ejecting apparatus is configured to eject an ink by an inkjet method, and includes an inkjet head configured to eject the ink. The inkjet head has a nozzle configured to eject the ink. The ink includes a resin particle having a size capable of passing through the nozzle. The resin particle contains a fibrous substance. The fibrous substance is, for example, fibers of cellulose.

Provided is an ink for use in electronic component production making use of screen printing, which is suitable for actually allowing fine lines with high precision to be drawn in screen printing, and for actually allowing successive screen printing operations to be performed. The ink for screen printing of the present invention includes surface-modified silver nanoparticles (A) and a solvent (B), and has a viscosity at a shear rate of 10 (1/s) and 25° C. of 60 Pa.Math.s or more. The surface-modified silver nanoparticles (A) each include a silver nanoparticle and an amine-containing protective agent coating the silver nanoparticle. The solvent (B) includes at least a terpene solvent. In solvent (B), a content of solvents having a boiling point of less than 130° C. is 20 wt % or less based on the total amount of solvents.
