Abstract: A method for handwriting input display, a device thereof and a computer-readable storage medium. The method for handwriting input display includes: receiving and displaying a first input of a user, wherein the first input is one or more first contents input in a handwriting way; receiving and displaying a second input of the user, wherein the second input is a mark line for highlighting the one or more first contents, and the mark line contains an overlapping area with the one or more first contents; and adjusting a line width of the mark line according to a height of a first content of the overlapping area.

Abstract: The present invention relates to a color-developing agent resin composition, which contains: (1) a phenolic resin represented by formula I; and (2) a blend of graft copolymers of a phenolic resin and a multivalent metal salt polymer of a substituted aryl carboxylic acid, said graft copolymers are represented by (II) and (III). The present invention further relates to a resin emulsion containing the color-developing agent resin composition and a method for preparing the same. The color-developing agent resin composition and the color-developing agent resin emulsion of the present invention are used for no-carbon copying paper as special resin color-developing agents. They have advantages of not only fast developing at a low temperature and bright colors, but also heavy developing strength and good light-aging resistance of writing, and furthermore, their coatings are not easy to turn yellow when they are hold in the air, and the like.
