Abstract: There is provided a method of making an aqueous dispersion wherein said dispersion comprises (A) one or more thickener and (B) solid particles of 1,2-benzisothiazolin-3-one, wherein said method comprises the steps of (a) forming an aqueous mixture (I) comprising water, a dissolved salt of 1,2-benzisothiazolin-3-one, and optionally one or more thickener, wherein the pH of said aqueous mixture (I) is 8.5 or higher, and (b) subsequently forming said aqueous dispersion by mixing together, in any order, components, wherein said components comprise an acid, said aqueous mixture (I), and optionally one or more thickener, wherein the pH of said dispersion is 1.5 to 7.5. Also provided is an aqueous dispersion made by that method.

Abstract: Tread for a tire for the driven axle of a heavy goods vehicle, comprising a plurality of circumferential grooves delimiting at least three ribs each having a height and a width measured in the axial direction, axially delimited by two edge rows, each rib having a plurality of sipes able to close at least in part as they enter the contact patch, and opening onto each lateral face of the rib to form two edge corners and having a depth at least equal to 50% of the height of the rib, these sipes in pairs delimiting an elementary rib volume and an elementary contact surface, wherein each elementary volume delimited by two sipes of one and the same rib has a void volume opening on the contact face in the new state, having a total area on the tread surface at least equal to 0.4% and at most equal to 1.

Abstract: A composite film suitable as a donor support in a radiation-induced thermal transfer imaging process, said film comprising a polymeric substrate and a transfer-assist coating layer derived from an aqueous composition comprising one or more water-soluble or water-dispersible radiation-absorbing compound(s).

Abstract: A donor element useful in an assemblage for imaging by exposure to light comprises a support layer formed by a stretching process, a light-to-heat conversion layer disposed adjacent the support layer containing a light absorber, and a transfer layer disposed adjacent the light-to-heat conversion layer opposite the support layer. The light-to-heat conversion layer is coated on the support prior to completion of the stretching process.

Abstract: A high solids replenishable electrostatic liquid developer concentrate includes toner particles containing a carboxyl terminated polyester resin and a pigment and a liquid toner dispensant. The solids content of the concentrate is above about 50%. A method for producing the concentrate includes the steps of blending particles containing a carboxyl terminated polyester and a pigment with a liquid toner dispersants to form a toner dispersant mixture and to increase the solids content of the toner dispersant mixture to more than about 90% solids. Toner solids in a liquid electrostatic developer are replenished by adding the toner particles to a toner solids depleted liquid electrostatic developer in a liquid electrostatographic printing machine.

Abstract: A dry toner is added to a liquid carrier to replenish a liquid developer in an electrostatographic printing machine.

Abstract: A high solids replenishable electrostatic liquid developer concentrate contains toner particles formed from a urethane modified polyester. This composition can be concentrated up to toner solids and subsequently sonicated to a working strength dilution.
