摘要:
A redispersible or soluble product, optionally having a solids content higher than 10% by weight, obtainable by freeze drying an aqueous dispersion of a latex comprising a polyanion and a polymer or copolymer of a substituted or unsubstituted thiophene; a printing ink comprising the above product; a coating dispersion or solution comprising the above product; and a method for making an antistatic or electroconductive layer comprising the steps of redispersing or diluting the above product by adding water or an organic solvent so as to obtain a dispersion or solution, optionally adding other ingredients to the coating solution or dispersion and applying the dispersion or solution to an object.
摘要:
According to the present invention there is provided a heat-sensitive imaging element for making lithographic printing plates. The heat-sensitive imaging element comprises an image-forming layer comprising hydrophobic thermoplastic polymer particles having a specific particle size and polydispersity for obtaining printing plates with an improved sensitivity, excellent developability, high throughput and less scumming.
