microcapsule used for carbonless copy paper

The wall of the capsule is made of melamine formaldehyde resin.microcapsule is used as CB and CFB of carbonless copy paper

It is used for carbonless copy paper(CB or CFB),It enjoys the following adcantages:rapid color development at low temperature,good color intensity and slow light-resistant aging.

The wall of the capsule is made of melamine formaldehyde resin.The core is the synthetic product of SRS-101(diaryl ethane) and colorless dyestuff CVL.In actual application the capsule shows excellent physico-chemical property.
