The invention relates to novel compounds of the following formula, in which R
1
, R
2
and R
3
, identical or different, independently represent hydrogen, a halogen, a Cl to C15 hydroxy or hydroxyalkyl group, and/or a C1 to C15 linear or branched alkyl group. R
4
is linked to the naphthalene unit at position 1, 2 or 3 via a —CH
2
—O— bond and R
5
is linked to the naphthalene unit at position 1, 2 or 3 and e is an integer lying between 0 and 2 and such that d+e=3. It also relates to the method for synthesizing these compounds and to their use for the manufacture of photochromic or photosensitive polymers.

The invention relates to novel compounds of formula (I):
in which
R
1
, R
2
and R
3
, identical or different, independently represent:
hydrogen
a halogen
a C1 to C15 hydroxy or hydroxyalkyl group
a C1 to C15 linear or branched alkyl group a, b and c independently lying between 0 and 5.
R
4
is linked to the naphthalene unit at position 1, 2 or 3 via a —CH
2
—O— bond and represents:
either a divalent group which is (co)polymerisable with a monomer; in which case d lies between 1 and 3
or a monovalent group which is (co)polymerisable with a monomer; in which case d is equal to 2 or 3 and
R
5
is linked to the naphthalene unit at position 1, 2 or 3 and represents:
hydrogen,
a halogen,
a C1 to C15 hydroxyalkyl group,
a C1 to C15 linear or branched alkyl group,
and e is an integer lying between 0 and 2 and such that d+e=3.
It also relates to the method for synthesising these compounds and to their use for the manufacture of photochromic or photosensitive polymers.
