    摘要： The invention relates to a method for encapsulating a solution, which consists of color reaction partners of color reaction systems while being provided in an aqueous emulsion, by using conventional microencapsulation methods. According to the invention, the color reaction partner is firstly dissolved in a solvent, and a nonsolvent that, at most, slightly dissolves the color reaction partner is admixed with rapid mixing to the solution obtained in the aforementioned manner. The nonsolvent is admixed in an amount that results in a supersaturated solution. The supersaturated solution is immediately emulsified with rapid mixing in the aqueous phase, and the encapsulation is carried out immediately afterwards. A vegetable oil C1-C8 alkyl ester is used in the solvent. This method exhibits both economic and technological advantages while enabling the production of microcapsules having an advantageously tight monomodal particle distribution that leads to an improved print rate.

    摘要： Product package (14), comprising a data storage device (10), packaging material, and an authentication system. The authentication system comprises first and second coatings (20, 24) coated on the storage device (10) and the packaging material. One of the coatings (20, 24) comprises chromogenic microcapsules capable of reacting to produce color. The other coating (20, 24) comprises color developer. The coatings (20, 24) can be bonded to each other or a composite coating can be a self-contained color former such as on the storage device (10). The invention further comprises methods of affirming authenticity of a data storage device (10). The method comprises reacting the chemical compositions to produce the color as an indication of authenticity of the data storage device (10).
