Claims71
A fluorescent pigment composition comprising:
- a) a polyamide, and
- b) a pigment of formula (Ib)
- 18
- in an amount of less than one percent by weight, wherein the percent by weight is based upon the weight of the polyamide.
A fluorescent pigment composition comprising:
- a) a polyamide,
- b) a pigment of formula (Ib)
- 23
- in an amount of less than one percent by weight, and
- c) a compound of the formula (XIII)
- 24
An article comprising:
- a) a polyamide, and
- b) a pigment of formula (Ib)
- 25
- in an amount of less than one percent by weight, wherein the percent by weight is based upon the weight of the polyamide.
An article comprising:
- a) a polyamide,
- b) a pigment of formula (Ib)
- 28
- in an amount of less than one percent by weight, wherein the percent by weight is based upon the weight of the polyamide, and
- c) a compound of the formula (XIII)
- 29
A fluorescent pigment composition comprising:
- a) a polyamide, and
- b) a pigment of formula (Ia)
- 30
- in an amount of less than one percent by weight, wherein the percent by weight is based upon the weight of the polyamide.
A fluorescent pigment composition comprising:
- a) a polyamide,
- b) a pigment of formula (Ia)
- 35
- in an amount of less than one percent by weight, wherein the percent by weight is based upon the weight of the polyamide, and
- c) a compound of the formula (XIII)
- 36
An article comprising
- a) a polyamide, and
- b) a pigment of formula (Ia)
- 37
- in an amount of less than one percent by weight, wherein the percent by weight is based upon the weight of the polyamide.
An article comprising:
- a) a polyamide,
- b) a pigment of formula (Ia)
- 40
- in an amount of less than one percent by weight, wherein the percent by weight is based upon the weight of the polyamide, and
- c) a compound of the formula (XIII)
- 41
A process of preparing a fluorescent pigment composition, the process comprising:
- a) incorporating a compound of formula (Ia)
- 42
- or a compound of formula (Ib)
- 43
- in a carrier polymer to form a masterbatch, and
- b) adding the masterbatch to a polyamide to form the fluorescent pigment composition.
A process of preparing a fluorescent pigment composition, the process comprising:
- a) physically mixing an additive with a compound of the formula (Ia)
- 45
- or a compound of the formula (Ib)
- 46
- to form a physical mixture,
- b) adding the physical mixture to a polyamide to form the fluorescent pigment composition.
A process of preparing a fluorescent pigment composition, the process comprising:
- a) obtaining a masterbatch comprising a compound of formula (Ia)
- 48
- or a compound of formula (Ib)
- 49
- b) obtaining a masterbatch comprising an additive,
- c) letting down the masterbatches independently, and
- d) adding the masterbatches to a polyamide to form a fluorescent pigment composition.
