PURPOSE: Crosslinkable LC organosiloxane with increased UV stability is provided which is produced from a crosslinking agent component with better suitability. CONSTITUTION: A crosslinkable LC organosiloxane comprises the unit of a general formula(1): £R_bMes_cSiO_(4-b-c)/2|, herein R is C1-C4-alkyl radical, Mes is at least one radical selected between a formula (2): -(CH2)p-(O)q-A£B-A|r-E-F-VN and a formula (3): -(CH2)m-(O)n-(A)t-Q-X, wherein A is a divalent radical among the group consisting of 1,4-cyclohexylene ring, 4,4'-bicyclohexylene radical, 1,4-phenylene ring, 2,6-naphthalene radical, 2,7-naphthalene radical, 2,5-(1,3-dioxanylene) ring and pyrimidinyl radical. and (3), b is 0, 1 or 2, c is 0, 1, 2, 3 or 4 and b+c≤4. |
