FIELD OF THE INVENTION
The present invention relates to a copolymer containing reactive silyl groups, a composition comprising the same, and a treating method using the same. Particularly, the present invention relates to: a copolymer, which forms a strong coating of the cross-linked copolymer which has resistance to washing on the surface of hair, skin or other materials. The invention is useful effects in the fields of cosmetics and the others. It had a modifying effect of the nature of hair, improves the effect of make-up retention and has a water-repellent effect.
BACKGROUND OF THE INVENTION
Numerous film-forming ingredients are used in the field of cosmetics and the other fields for the purpose of giving various effects.
However, there are very few film-forming ingredients that have a useful effect as a cosmetic ingredient and which maintain the effect against washing with shampoo or detergent.
Also, in the field where water-repellents give water-repellency to fibers, paper or the other materials, it is expected to improve resistance to washing.
SUMMARY OF THE INVENTION
The first object of the present invention is to find a compound that can form a coating, wherein said coating can exhibit cosmetically useful effects such as a hair-nature modifying effect, an improving effect of the retention of hair colorants or make-up cosmetics, and skin-protecting effect. These effects are maintained due to a high resistance to washing. It is a further object to provide a composition comprising the compound.
Also, the second object of the present invention is to find a compound that can form a coating, which is excellent in water-repellency and resistance to washing when on materials to be treated such as fibers. It is a further object to provide a composition comprising the compound.
It has been found that a strong coating of a cross-inked copolymer that is excellent in resistance to washing can be formed when a copolymer containing a silyl group that one or more reactive functional groups are bonded to (e.g., a trifunctional silyl group) is crosslinked with hydrolysis on the material to be treated such as hair or skin.
Also, it has been found that such cross-linked coating has a hair-nature modifying effect and a skin-protecting effect, and these effects are maintained without loss even with repeated shampooing.
Also, it has been found that the cross-linked coating formed by such copolymer ameliorates resistance to washing off of make-up cosmetics such as temporary hair colorant, acidic hair dye, mascara or nail enamel and improves make-up retention.
Also, it has been found that a cosmetic pack comprising the copolymer has a good skin-cleaning characteristic and is excellent in applicability, strippability and film strength.
Further, a coating which has high water-repellency, resistance to fouling and suitability as a sizing and which is excellent in resistance to washing can be formed even when the copolymer is treated on other materials such as fibers, paper or glass.
A composition of the present invention comprises a copolymer containing silyl groups wherein each silyl group has at least one reactive functional group bonded thereto.
The silyl group has at least one reactive functional group bonded thereto that can cross-link molecules of the copolymer by forming a siloxane bond Si—O—Si with hydrolysis.
Also it is preferable that, as one of the constituent monomers, the copolymer comprises Monomer (A) shown by the following Formula (I):
wherein Ris a hydrogen atom or methyl group; R
2
is an alkylene group having 1-6 carbon atoms; and R
3
, R
4
and R
5
each is a reactive functional group which can cross-link molecules of the copolymer hydrolyzing.
Also, it is preferable that, as one of the constituent monomers, the copolymer further comprises Monomer (B) shown by the following Formula (II):
wherein R
6
is a hydrogen atom or methyl group; and R
7
is an alkyl group having 1-18 carbon atoms.
Also, it is preferable that as one of the constituent monomers, the copolymer further comprises Monomer (C) shown by the following Formula (III):
wherein R
8

x
2
is an integer of positive number.
It is preferable that the percentage of Monomer (A) in the copolymer is 25 to 99 wt %.
Also, it is preferable that the percentage of Monomer (B) in the copolymer is 1 wt % or more.
Also, it is preferable that the percentage of Monomer (C) in the copolymer is 1 wt % or more.
Also, the copolymer can further comprise a constituent Monomer (D) shown by the following Formula (VII):
wherein R
13
is a hydrogen atom or methyl group; R
14
is an alkylene group having 1-6 carbon atoms; and Y is a group shown by —N
+
