wherein
R is an non-hydrophilic aliphatic or cycloaliphatic group containing from 8 to 40 carbon atoms;
m is 1 or 2;
R¹ is NO₂, CN or COOR²;
R² is H or C₁₋₄-alkyl;
n is from 1 to 4
and R³ is H, a metal or a group containing a tetravalent N atom and a second NLO compound of the formula:
wherein T is H, a metal or a group containing a tetravalent N atom;
T¹ is NO₂, CN or COOY; Y is selected from H, C₁₋₄-alkyl, a metal or a group containing a tetravalent N atom;
T² & T³ are each independently H or a non-hydrophilic aliphatic or cycloaliphatic group containing up to 30 carbon atoms;
T⁴ & T⁵ are each independently H or a non-hydrophilic aliphatic or cycloaliphatic group containing up to 30 carbon atoms;
and T⁶ & T⁷ are each independently H or a non-hydrophilic group containing up to 4 carbon atoms;
