It is the condensation product of a compound of formula (1) and a compound of formula (2).R101, R102=H or 1-18C alkyl.    TECHNOLOGY FOCUS - POLYMERS - Preferred Parameter: The absorption maximum of microencapsulated luminescent pigment is between 350-500 nm. The emission maximum is between 600-700 nm. The Stokes shift is greater than or equal to120 nm. The microencapsulated luminescent pigment has an average particle size of 0.8-50 mu. The weight ratio of microcapsule-forming material to microencapsulated luminescent pigment is 0.001:1-1:1. The polymer composition is in the form of a film with a thickness of 10-300 mu. Preferred Component: The polymer of the shell is crosslinked by in situ polymerization. The crosslinked polymer of the shell is polyamides, polyureas, polyurethane's, polyacrylates, polymethacrylates, polystyrenes, polyvinylpyridines, polyacrylonitriles, polyepoxides, gelatin, poly (vinyl alcohol), cellulose derivatives, silica's, silicone resins, preferably melamine-formaldehydes, urea-formaldehydes, or phenol-formaldehydes. The microencapsulated luminescent pigment contains in the microcapsule, a further additive consisting antioxidants, phosphites or phosphonites, UV-absorbers, light stabilizers, singlet oxygen quenchers, further fluorescent dyes or pigments, processing aids, antistatic agents, antifog additives, fillers, or reinforcing materials. The film is a multilayer construction of between 2-7 polymer layers containing microencapsulated luminescent pigment in greater than or equal to1 layer. ACTIVITY - Plant Growth Regulant.    MECHANISM OF ACTION - None given.    EXAMPLE - Into a 1-L reactor, 300 ml deionized water was charged in followed by adding 10 drops of polyethylene glycol 300 to water. The contents of the reactor were warmed to 60degreesC by a thermostatic water bath. Next, 17g of 50% PIAMID M50(RTM: melamine formaldehyde resin) and 10 ml 2 N amidosulfonic acid were added respectively. After 1 minute, 60 g Smartlight RL1000(RTM: Not defined) luminescent pigment was added; and the stirring speed was increased to 1400 revolutions/minute (rpm) to disperse the pigment particles. After 10 minutes dispersion, the stirrer speed was reduced to 800 rpm. Then, the resulting aqueous dispersion was maintained at 60degreesC for 2 hours to complete the encapsulating of the pigment particles. The microencapsulated pigment dispersion was then allowed to cool to room temperature. The microencapsulated pigments were recovered by filtration, washing with water, and then vacuum drying at 60degreesC. The microencapsulated particles had particle size of 1-15 microns with shell thickness of 50-100 nm. Encapsulated pigment luminesced much stronger than non-encapsulated. When measured with the same instrumental parameters, the ratio was 6:1.
