Aqueous ink of pigment type

An aqueous ink for ink jet recording comprises a dye and a polymeric compound which can undergo a decarboxylation reaction. In an ink jet recording method, a recording operation is carried out by jetting a liquid droplet of the ink from a nozzle to a recording medium by using thermal energy.

Disclosed is a thermal transfer recording medium comprising a substrate provided thereon at least an ink layer which is to be transferred by heat application, characterized in that the loss tangent (tan .delta.) of the ink layer in viscoelasticity measurement at a temperature of from 60.degree. to 100.degree. C. ranges from 0.4 to 2.5.

Thermal transfer recording medium

A developer composition comprising a carrier, whose surface layer comprises a silicone resin having a urethane bond, and a toner, which is little affected by environmental factors, so that it can develop good electrostatic latent images even under low-temperature and low-humidity conditions and under high-temperature and high-humidity conditions, to give high-quality prints.

Developer composition for electrostatic latent images

A developer composition for an electrostatic charge image, which comprises a toner comprising a binder resin and a coloring agent, and 0.1 to 1.0% by weight of fine polymer particles with a glass transition temperature of 90.degree. C. or higher deposited on the surface of the toner, the binder resin comprising, as a main component, a polyester resin with an OHV/AV value of 1.2 or more wherein OHV and AV represent the hydroxyl value and acid value of the polyester resin, respectively.

Electrostatic charge image developer composition
