Inks for ink jet printers containing an aqueous carrier medium; a pigment; a polymeric dispersant; and an emulsion polymer additive stabilized with a structured polymer are stable, have low viscosity, exhibit excellent print quality, provide excellent smear resistance after drying, have good decap and crusting time, and also demonstrate good charging stability when used in continuous flow printers.

Ink jet inks containing emulsion polymer additives stabilized with

An ink/media set is provided having improved durability. The ink contains an aqueous medium and a dye or pigment dispersion as the colorant. The media has a coating that contains a hydrophilic polymer and a reactive component. The printed media is exposed to an energy source that binds the ink to the media coating, and renders the coating more durable.

A laser-induced melt transfer process is described in which a melt viscosity modifier is used to facilitate the melt transfer process.

Laser-induced melt transfer process

A laser-induced melt transfer process is described which utilizes a melt viscosity modifier and in which a post-transfer treatment is used to substantially eliminate back-transfer.

Laser-induced thermal transfer process

A blend of a methacrylate, acrylate or styrene polymer; selected ethylene terpolymers, and carbon black is useful to add to polyvinyl chloride polymers to make molding resins.

Molding components

A blend of polyvinyl chloride, a methacrylate, acrylate or styrene polymer, selected ethylene terpolymers, and carbon black is useful to make polyvinyl chloride molded articles.

Molding compositions

Soft thermoplastic segmented copolyester elastomers consisting essentially of a multiplicity of recurring short chain ester units and long chain ester units joined through ester linkages, said short chain ester units amounting to about 15 to less than 30 percent by weight of said copolyester and being derived from a mixture of aromatic dicarboxylic acids such as a mixture of terephthalic acid and isophthalic acid containing about 55 to 95 percent by weight of terephthalic acid, and butanediol, and said long chain ester units amounting to more than 70 to 85 percent by weight of said copolyester and being derived from a mixture of aromatic dicarboxylic acids such as a mixture of terephthalic acid and isophthalic acid containing about 55 to 95 percent by weight of terephthalic acid, and polytetramethylene ether glycol having an average molecular weight of about 1500 to 3500, said copolyester having a melt index of less than about 30 and a melting point of about 90.degree. to 130.degree.C. give superior performance when formulated into pressure sensitive adhesives. Such adhesive compositions comprise (A) about 1 to 99 percent by weight of the soft thermoplastic segmented copolyester and (B) about 1 to 99 percent by weight of one or more low molecular weight thermoplastic resins.
