Abstract

Aspects of the invention are directed to characteristics and parameters of color coatings on keratin fibers. The color coatings are produced from compositions of several kinds of polymers that enable the color coatings to exhibit adherence, remanence, wear fastness and resistance to environmental attack.

Claims46

Dependent claims

A composition for treating keratinous surfaces, comprising a preformed composition or a reactive composition wherein:

a) The preformed composition comprises a medium and a preformed polymer of organic, silicone or organosilicone construction having multiple numbers of non-reactive functional groups distributed within the polymer chain(s) and/or distributed as pendant groups along the polymer chain, the functional groups comprising one or more of urethan, urea, ester, amide, hydroxyl, amine and carboxyl groups and any combination thereof;
the distribution of the non-reactive functional groups per preformed polymer molecule being in a range from one per 1000 monomeric units to one per 10 monomeric units;
b) The reactive composition comprises a medium and first and second components, the first component comprising an organic, silicone or organosilicone polymer having first reactive functional groups and the second component comprising an organic, silicone or organosilicone in situ linking material having reactive second functional groups wherein the first and second reactive functional groups are complementary reactive pairs and can form covalent linkages in situ to form an in situ polymer product of organic, silicone or organosilicone configuration;
c) The preformed polymer and the in situ polymer product have a wt avg molecular weight range of at least about 1 KDa;
d) The first and second components have a wt avg molecular weight range of from about 120 Da to about 500 KDa and have complementary reactive group densities of at least about 1 per first and/or second component molecule;
e) The first and second components optionally have in chain and/pendant non-reactive functional groups that do not in situ react with the complementary reactive pairs;
f) The preformed polymer has a linear configuration or an optional cross-linked configuration wherein the cross-linked configuration comprises at least 1 cross-link per 10 molecules and the cross links provide a branched, star or network configuration of the preformed polymer.

4 more elements

A composition according to any of the preceding claims wherein the preformed composition and/or the reactive composition further comprise an additive selected from one or more of a microfibril, a filler material, a polyolefin as macromolecular strands or nanoparticles, a carbon nanotube, a nanofiller of graphite oxide mixed polymer, a graphene, a UV filter, a radical scavenger, a triplet formation inhibitor, a metal compound which can absorb or reflect UV light, polyvinylidene fluoride.

A composition according to any of the preceding claims wherein the pigment particles are a blended combination of organic and/or inorganic pigment microparticles of differing visible colors, shades and hues matched according to a color gamut for blends selected to include at least one or more of Pigment Yellow 83, Pigment Green 36, Pigment Blue 60, Pigment Blue 66, Pigment Blue 16, Pigment Black 6, Pigment White 6, Pigment Red 122, Pigment Red 5, Pigment Red 112, Pigment Violet 19, aluminum flakes, copper flakes, brass flakes.
