  • Patent number: 6759455
    Abstract: This invention discloses a resin which is particularly useful in making paraffinic solvent based paints, said resin being comprised of repeat units which are derived from (a) about 5 to about 60 weight percent tertiary-butyl cyclohexyl methacrylate, (b) 0 to about 40 weight percent vinyl aromatic monomers, (c) about 20 to about 80 weight percent alkyl methacrylate monomers, and (d) about 1 to about 30 weight percent alkyl acrylate monomers. These resins exhibit good hardness and excellent resistance to ultraviolet light. More importantly, coatings made with these resins are highly resistant to yellowing and discoloration on exposure to ultra-violet light over long periods of time.

  • Publication number: 20040106725
    Abstract: A polystyrene seed latex composition is provided having a total emulsion polymer content of from 0.2 to 2.0 weight percent and a particle diameter less than 150 Å. The seed latex is produced on a continuous basis by feeding to a continuous stirred reactor an emulsion stream and initiator stream. The feed streams are mixed in the stirred reactor at room temperature to produce the seed latex. Preferably, the initiator stream comprises a sodium formaldehyde sulfoxylate reducing agent. The amount of initiator charged into the continuous seed reactor is sufficient to complete both the seed and a subsequent continuous latex polymerization reaction.

    Abstract: A marking composition is disclosed for placing a temporarily visible mark on a surface. The composition includes a paint base and a pigmented colorant. The pigmented colorant is dispersed within the paint base, and has characteristics that cause the mark to progressively become substantially invisible upon exposure to UV light. Additives, such as UV absorbers and anti-oxidants may be included to alter the rate at which the mark becomes invisible. The pigmented colorant may be a dispersion of dyed melamine-toluenesulfonamide-formaldehyde polymer in a mixture of alkyl based resins and aliphatic hydrocarbons. The colorant may be about 2 to 30 parts by weight of the composition. In one embodiment, the pigmented colorant is a Special Fugitive Colorant, with a color selected from the group consisting of: Special Fugitive Yellow Dispersion, No. 121M6669; Special Fugitive Orange Dispersion, No. 121M6665; Special Fugitive Red Dispersion, No. 121M6850; Special Fugitive Red Dispersion; No.
