fixative
A clear solution, such as a synthetic resin in
xylene (C 8 H 10 ) sprayed
or coated on a work of art, a reproduction copy,
etc., that "fixes" or stabilizes the image, thus
making it more resistant to wear, smudging, etc.
Fixatives protect and preserve, but they also at
times change the refractive index and may also
impart an unnatural sheen to the colors, possibly
one not intended by the artist. (233 )
