  • Patent number: 5952404
    Abstract: An aqueous gloss emulsion paint comprises a dispersion of structured composite particles, said structured particles comprising an association of particles of inorganic pigment and polymeric particles. The polymeric particles are formed from a polymer or copolymer having a minimum film forming temperature not greater than 50.degree. C. The component particles of the composite particles are held in association as a result of surface charges on the particles said surface charges on the polymeric particles being of opposite sign to the surface charge on the particles of inorganic pigment. The ratio of polymeric particles to particles of inorganic pigment in the composite particles is from 0.5:1 to 6:1 by volume.

  • Patent number: 5948481
    Abstract: A coated transparency, and method for making it, is disclosed, the transparency having a multi-layer antireflection coating that provides high transmittance with low specular reflectance, yet that also provides reduced visibility of surface defects. The coating includes alternating layers of polymerized silicon dioxide and polymerized titanium dioxide on a transparent substrate, with at least one of the layers incorporating discrete particles having a refractive index different from that of surrounding polymer. This provides the coating with a diffuse reflectance that is comparable to, or larger than, its specular reflectance, yet that still is negligible when compared to the coating's transmittance. The diffuse reflectance creates a loss of contrast for any reflected image or glare, thus masking any surface defects and providing a comfortable visual appearance.

  • Patent number: 5945357
    Abstract: A multi-layer papermaking fabric for use in a papermaking machine. The multi-layer fabric includes an upper fabric layer having a paper fiber support surface which is formed of first warp yarns interlaced with first weft yarns with at least one of these being knit yarns. Also, the lower fabric layer is formed of second warp yarns interlaced with second weft yarns. The construction of the knit yarns forms a series of loops which extend longitudinally and transversely of their longitudinal axis. These loops form the support surface with increased cover and provide for more uniform drainage of the paper forming fibers.

  • Patent number: 5939341
    Abstract: There is provided a laminate of nonwoven fabrics for outdoor applications which has good resistance to ultraviolet light. The laminate has two meltblown layers sandwiched between spunbond layers to produce an SMMS laminate. The layers have a large amount of a UV stabilizer and metal oxide pigments. Such laminates are useful for car covers, awnings and canopies, etc. When the laminate is used as a car cover, it is preferred to skew the basis weights of the outer layers so that the layer against the car is significantly lighter than the other outer layer and to reduce the denier of the fibers in the layer against the car.
