  • Radiation curable coating having low gloss and coated articles made therefrom
    Patent number: 6787225
    Abstract: A radiation curable coating comprising: (i) at least one radiation polymerizable reactant; (ii) at least one initiator for initiating cure; (iii) at least one wax; wherein the wax is present in an amount sufficient to reduce the 60° gloss of the cured coating to a gloss level less than 40 when the coating is cured by exposure to radiation in the presence of oxygen to provide a dry film thickness of 1.0±0.1 mil.

  • UV curable coatings having improved weatherability
    Patent number: 5559163
    Abstract: UV curable coatings comprising at least one photoinitiator and at least one photopolymerizable UV absorber, wherein the photoinitiator has the ability to absorb a significant portion of the total energy needed to cure the coating from wavelengths in which the UV absorber does not appreciably absorb.

  • Process for manufacturing painted backlit displays having uniform backlighting intensity
    Patent number: 5432684
    Abstract: A method is provided for producing an illuminated graphic display composed of non-flat molded plastic backlit components which serve as interior controls for an instrument panel of an automobile. The method involves a process by which such backlit components are manufactured so as to result in minimal variability of backlighting intensity. The method particularly involves molding each backlit component from a white translucent substrate whose thickness is individually tailored such that the backlit component exhibits a suitable level of backlighting intensity when illuminated by a minimal number of light sources. For daytime viewing, a suitable and uniform level of graphics whiteness for the group of backlit components is achieved by painting each substrate with a white translucent coating, such that the backlit components have similar reflective characteristics.
