A blend with better properties could be obtained by adding phenolic resin 2402/tin bichloride (8/0. 5) curative and a certain level of dioctyl phthalate plasticizer and HAF reinforcing agent.

This standard ensures that this tea is of the highest possible quality and that the blend has retained a high level of valuable essential oils - on average twice as high as ordinary herb teas.

Thus, we propose that the blend of a full-color image can be viewed as superposition of two complementary gray - level transformation images.
