The surfactants of this invention are phenolic-formaldehyde resins that have been sulfomethylated with from 1-13 moles of sulfomethylation per 1000 grams of the starting resin and further modified by reaction with up to 20 moles, preferably 0.25 to 10 moles, per 1000 grams of starting resin of a blocking agent of the type X(CHR).sub.m (CH.sub.2).sub.n Y, wherein X is a halogen, an activated double bond, epoxy ring or halohydrin, Y is a property group such as sulfonate, phosphonate, carboxylate or hydroxyl, R is another property group such as hydrogen, hydroxyl, mercaptan or amine, and n and m are integers from 0 to 5, with n or m being at least 1, to at least partially block the phenolic hydroxyl group of the resin. The phenolic-formaldehyde resin may also be cross-linked to tailor its molecular weight and then treated with urea or ammonia, if desired. |

The disclosure discloses a method of preparing electric and temperature dual-control bi-stable color-changing dyes and microcapsules, belonging to the technical fields of fine chemicals and materials science. According to the disclosure, after an electrolyte, a leuco dye and an organic solid material are mixed according to 1:(2-10):(15-50), a series of electric and temperature dual-control bi-stable color-changing dye compounds having a color change temperature range of −5° C. to +80° C. can be prepared. The dye compounds change color under cooperative control of electricity and temperature, and can be continuously stable at a certain color change state according to different conditions, and finally achieve controllable color change conditions and controllable color change stable states. When being driven by voltage and temperature, the dual-control bi-stable color-changing microcapsules prepared according to the disclosure achieve controllable color change performance and color change stable states, and have the driving voltage being lower than 10 V (much lower than the human body safety voltage 36 V). |
