Abstract
Gloss in surface coating compositions is increased by admixing a sol or gel containing salt with a polymer and a surface coating paste stock. A novel surface coating composition containing a polymer and salt homogeneously distributed in the composition is prepared from the sol or gel and has increased specular gloss compared to a composition without the admixed sol or gel.

A resultant dried composition containing a polymer and salt components and formed by drying a product surface coating composition prepared by the method comprising the step of admixing a sol or gel composition containing a gloss-enhancing concentration of a salt in the form of anions, cations and/or colloidal salt particulates with a composition containing a polymer to produce a product surface coating composition or a surface coating precursor composition, said product surface coating composition or a product surface coating composition derived from said surface coating precursor composition both providing a gloss property to said resultant dried composition which is greater than said gloss property of the same product surface coating composition prepared without said salt from said sol or gel composition.
A resultant dried composition containing a polymer and salt components and formed by drying a product paint composition prepared by the method comprising the step of admixing a sol or gel composition containing a salt in the form of anions, cations and/or colloidal salt particulates with a paint composition or a paint precursor composition, said paint composition, product paint composition or paint precursor composition each containing a polymer.
A resultant dried composition containing a polymer and salt components and formed by drying a surface coating composition prepared by the method comprising the following steps:
- (a) admixing a sol or gel composition containing a salt and having a pH less than about 4.0 with a composition containing a latex of a polymer to produce a product admixture composition containing said salt and said latex of a polymer;
- and
- (b) blending said product admixture composition with a surface coating paste stock containing one or more components selected from the group consisting of a pigment, an extender pigment, a coalescing aid, a thickening aid, a dispersing aid, a protective colloid, a defoamer, a biocide, an amine solubilizer, a flow additive, a drier, a cosolvent and a filler material, to produce a surface coating composition having a specular gloss which is greater by at least about 2 percent reflectance, based upon light having about a 60.degree. angle of incidence, than substantially the same surface coating composition but not containing said sol or gel composition.
A resultant dried composition containing a polymer and salt components and formed by drying a waterborne surface coating composition prepared by the method comprising the steps of:
- (1) admixing a composition containing a latex of a polymer with a surface coating paste stock containing one or more components selected from the group consisting of a pigment, an extender pigment, a coalescing aid, a thickening aid, a dispersing aid, a protective colloid, a defoamer, a biocide, an amine solubilizer, a flow additive, a drier, a cosolvent and a filler material, and
- (2) admixing a sol or gel composition containing a salt in the form of cations, anions, and/or colloidal salt particulates with the admixture composition obtained from step (1) to produce a surface coating composition containing said salt in a sufficient amount to enhance the gloss property of said surface coating composition.
A coated substrate having a surface at least partially coated with a dried surface coating composition comprising a polymer resulting from emulsion polymerization and salt components in the form of anions, cations and/or colloidal salt particulates wherein said salt components are derived from a salt-containing sol or gel composition having a nonaqueous solvent.
A coated substrate having a surface at least partially coated with a dried paint composition containing a polymer and salt components and prepared by the method comprising the steps of:
- (1) admixing a surface coating paste stock containing one or more components selected from the group consisting of a pigment, an extender pigment, a coalescing aid, a thickening aid, a dispersing aid, a protective colloid, a defoamer, a biocide, an amine solubilizer, a flow additive, a drier, a cosolvent and a filler material with a sol or gel composition containing a salt in the form of cations, anions and/or colloidal salt particulates, said salt in sufficient amount to enhance gloss on a substrate when coated on said substrate and
- (2) admixing a composition containing a latex of a polymer with an admixture composition obtained from step (1) to produce a surface coating composition having enhanced gloss properties compared to the same surface coating composition which does not contain said sol or gel composition.
A coated substrate having a surface at least partially coated with a dried paint composition comprising:
- (A) a surface coating paste stock containing one or more components selected from the group consisting of a pigment, an extender pigment, a coalescing aid, a thickening aid, a dispersing aid, a protective colloid, a defoamer, a biocide, an amine solubilizer, a flow additive, a drier, a cosolvent and a filler material.
- (B) a polymer resulting from emulsion polymerization,
- (C) a sol or gel composition having a pH less than about 4.0 and comprising
- (1) a stabilizer comprising a chelator or a nonionic surfactant, and
- (2) at least one salt comprising anions, cations and/or colloidal particulates, said salt in sufficient amount to enhance the gloss property of said composition when coated on said substrate.
