  • Curable coating compositions having improved effect pigment orientation and a method using the same
    Patent number: 6420472
    Abstract: There is described a curable coating composition having at least one effect pigment which, upon cure, exhibits substantially improved orientation of the effect pigment and a corresponding improvement in appearance. The composition comprises: (A) a carbamate-functional component having a hydrophobicity equivalent to or greater than that of a carbamate-functional compound (A′) which is the reaction product of: (1) a compound comprising a plurality of hydroxyl groups, at least one of which is the result of a ring-opening reaction between an epoxy group and an organic acid group, and (2) cyanic acid or a compound comprising a carbamate group, and (B) a component comprising a plurality of groups that are reactive with the carbamate functional groups on component (A), and (C) at least one effect pigment, the curable coating composition when cured having a substantially improved effect pigment orientation. Preferably, the composition further comprises particular rheology control agents.
    Type: Grant

  • Curable coating compositions having improved effect pigment orientation and a method of using the same
    Patent number: 6117931
    Abstract: There is described a curable coating composition having at least one effect pigment which, upon cure, exhibits substantially improved orientation of the effect pigment and a corresponding improvement in appearance. The composition comprises:(A) a carbamate-functional component having a hydrophobicity equivalent to or greater than that of a carbamate-functional compound (A') which is the reaction product of:(1) a compound comprising a plurality of hydroxyl groups, at least one of which is the result of a ring-opening reaction between an epoxy group and an organic acid group, and(2) cyanic acid or a compound comprising a carbamate group, and(B) a component comprising a plurality of groups that are reactive with the carbamate functional groups on component (A), and(C) at least one effect pigment,the curable coating composition when cured having a substantially improved effect pigment orientation. Preferably, the composition further comprises particular rheology control agents.
