  • Patent number: 6057385
    Abstract: The present invention provides a thermal transfer ink ribbon which has good ink transferability and is capable of producing transferred images which are sharp and have high durability. As the main constituent of a binding material of thermally fusible resin, fine particles of low slipperiness which are not softened at a temperature at which the binding material is softened are contained in an ink layer 13 when the ink layer 13 is deposited to produce a thermal transfer ink ribbon 1. Since the thermally fusible resin is used, the durability of transferred images is high. Because the fine particles are contained, the ink layer can be separated sharply from the thermal transfer ink ribbon 1. As the fine particles are of low slipperiness, no slippage occurs between the thermal transfer ink ribbon 1 and a transfer medium. The fine particles of low slipperiness have an average diameter ranging from 0.3 .mu.m to 3.0 .mu.

The colored enamel paint comprises: resin components, which include a polyesterpolyol and an acrylic polyol; a crosslinking agent, which includes a blocked isocyanate as the essential component and may further include a melamine resin; a blocked isocyanate dissociation catalyst, which at least includes a dibutyltin dicarboxylate; and a pigment. The clear paint comprises: a resin component, which includes an acrylic polyol; the crosslinking agent; and the blocked isocyanate dissociation catalyst.

  • Patent number: 5976706
    Abstract: Polyesterdiols having low viscosities of less than 3500 cps, high content of non-volatile matter in excess of 96 wt %, and narrow molecular weight distribution of less than about 1.4 are prepared by esterification of one or more aliphatic dicarboxylic acids or ester derivatives thereof using at least a 1.5 molar excess of one or more aliphatic diols until an acid number of less than 20 is achieved, and stripping excess diol from the polyesterdiol reaction product. Where esterification catalyst is used, catalyst is substantially removed prior to stripping excess unreacted diol from polyesterdiol reaction product. The polyesterdiols so produced are useful as (i) curable components in thermosettable resin compositions, particularly compositions essentially free of volatile organic solvent and also containing a crosslinking agent and a reactive hardening agent: and/or (ii) useful as coatings, paints and adhesives, providing coatings with very low content of volatile organic compounds.

  • Patent number: 5977208
    Abstract: The present invention provides a thermal transfer ink ribbon which has good ink transferability and is capable of producing transferred images which are sharp and have high durability. As the main constituent of a binding material of thermally fusible resin, fine particles of low slipperiness which are not softened at a temperature at which the binding material is softened are contained in an ink layer 13 when the ink layer 13 is deposited to produce a thermal transfer ink ribbon 1. Since the thermally fusible resin is used, the durability of transferred images is high. Because the fine particles are contained, the ink layer can be separated sharply from the thermal transfer ink ribbon 1. As the fine particles are of low slipperiness, no slippage occurs between the thermal transfer ink ribbon 1 and a transfer medium. The fine particles of low slipperiness have an average diameter ranging from 0.3 .mu.m to 3.0 .mu.

  • Patent number: 5972809
    Abstract: The present invention provides a waterborne coating composition which includes a polymeric film-forming resin. The polymeric film-forming resin includes a dispersion of polymeric microparticles prepared by forming, in aqueous medium, a mixture of: (a) an unsaturated, substantially hydrophobic polyester component, and (b) an ethylenically unsaturated monomer component. With various hydrophobic polyesters, the ethylenically unsaturated monomer component of the polymeric film-forming resin includes: (a) an acrylamide or methacrylamide with N-methylol or N-alkoxymethyl functionality, (b) an alpha-beta ethylenically unsaturated compound with carboxyl functionality, and (c) an alpha-beta ethylenically unsaturated compound with no additional reactive functionality. Such a waterborne coating composition has a low V.O.C., provides added stiffness, does not block, and can be applied in such a manner that it does not substantially mask the texture of the nonwoven fabrics and/or textiles over which it is applied.
