Ultraviolet ray absorbing polymer particle compositions |
(57) The present invention discloses an ultraviolet ray absorbing polymer particle. The
ultraviolet ray absorbing polymer particle includes an ultraviolet ray absorber and
a polymer of the formula:
(A)
x(B)
y
where A is a polyfunctional ethylenically unsaturated monomer, B is a monofunctional
ethylenically unsaturated monomer, x is 0.1 to 90 mole percent and y is (100-x) mole
percent. The ultraviolet ray absorbing particle is particularly useful in an imaging
element.
