WATER-DISPERSIBLE COPOLYMER CONTAINING UVA AND UVB LIGHT-ABSORBING MONOMERS |
| 摘要 |
The invention is concerned with novel water-dispersible or water-soluble copolymers which contain at least one UVA light-absorbing monomer, one UVB light-absorbing monomer, one hydrophilic monomer, and optionally one hydrophobic monomer component. The UVA light-absorbing monomer absorbs at lambda max ultraviolet light in the 320 - 400 nm range. The UVB light-absorbing monomer absorbs at lambda max ultraviolet light in the 290 - 320 nm range. |
