A pearlescent pigment which is a ferrite-coated iron oxide-coated platy substrate in which the ferrite is substantially free of crystallites is obtained by adding metal ions to a slurry of hydrous iron compound and platy particles and then co-calcining in the metal and iron.
Novel biphenyl derivatives of the general formula I in which R.sub.1, R.sub.1', R.sub.1'', R.sub.2, R.sub.2', R3 and n are as defined in Patent claim 1, stereoisomers thereof and physiologically acceptable salts or solvates thereof are novel integrin inhibitors which preferentially inhibit the .alpha..sub.v.beta..sub.6 integrin receptor. The novel compounds can be used, in particular, as medicaments ##STR00001##
A pearlescent pigment comprises (a) synthetic mica substrate, (b) calcined ferrite coating on the substrate, and (c) an outer layer or treatment wherein said outer layer or treatment was added to the calcined ferrite coated synthetic mica in water.The pearlescent pigment may be used in exterior applications such as automotive paint systems.
The invention provides a curable two layer effect providing coating system which provides a visual appearance and effect previously obtainable only with a curable three layer effect providing coating system. The two layer effect providing coating system of the invention consists essentially of a first layer consisting of a first coating composition (a), and a transparent second layer applied directly to the first layer and consisting of a second coating composition (b) comprising an effective amount of an interference metal oxide coated mica having a hue shift of at least 100.degree.. In a preferred embodiment of the invention the first coating composition (a) will be tinted so as to match the color of the second coating composition (b) when viewed at an angle of 110.degree. from vertical. Most preferably, the first coating composition (a) will comprise (i) at least 95 weight percent titanium dioxide pigment and (ii) no more than 5 weight percent of one or more tint pigments, all based on the total weight of the first coating composition (a).
A thermal transfer assembly that comprises a thermal transfer ribbon and a covercoated transfer sheet. The thermal transfer ribbon includes a support and a ceramic ink layer. The ceramic ink layer is present at a coating weight of from about 2 to about 15 grams per square meter, and it includes from about 15 to about 94.5 percent of a solid carbonaceous binder, and at least one of a film-forming glass frit, an opacifying agent and a colorant (at a combined level for the film forming glass frit, the opacifying agent and the colorant of at least 0.5 weight percent).
