Abstract: Provided are chlorine-free ink and coating compositions that demonstrate improved adherence when applied to untreated flexible plastic film substrates. The provided compositions eliminate the need for a separate step of pre-treating a plastic film before applying an ink or coating composition. Also provided are methods for producing a printed article using the provided ink and coating compositions and methods of adhering chlorine-free inks or coatings that exhibit improved adhesion characteristics to untreated plastic films.

Abstract: The present invention provides a urethane-forming reaction catalyst which is useful for catalyzing a reaction between an isocyanate compound, in particular, an aliphatic isocyanate and a hydroxyl group-containing compound to form a urethane material, which does not affect the performance of the urethane material, and which can be easily removed from the resulting urethane material, and a method for producing a metal compound-free urethane material using the urethane-forming reaction catalyst. The catalyst of the present invention is a urethane-forming reaction catalyst for producing a urethane material by allowing a hydroxyl group-containing compound to react with an isocyanate compound, the catalyst being at least one solid acid catalyst selected from the group consisting of a (A) composite metal oxide in which a metal oxide (A-2) or a non-metal compound (A-3) is carried on a surface of a metal oxide carrier (A-1), (B) zeolite, and a (C) heteropoly acid.

Abstract: A first fluid line couples first and second wheel cylinders. A second fluid line couples third and fourth wheel cylinders. A first pressure increasing unit increases pressure applied to the first and second wheel cylinders to a second pressure level which is greater than a first pressure generated by a master cylinder. When the first pressure increasing unit is in operation, a pressure difference setting unit sets a difference between pressure applied to the first and second wheel cylinders and pressure applied to the third and fourth wheel cylinders.

Abstract: A vehicle braking system can, for example when the performance of a booster has deteriorated, reduce a brake pedal depressing force required to obtain a sufficient braking force and thereby lighten the burden on the driver. A booster and a master cylinder generate a brake fluid pressure in correspondence with an operation of a brake pedal. Wheel cylinders connected to the master cylinder generate wheel braking forces in wheels of the vehicle. It is determined if a vehicle braking state corresponds to a state of operation of the brake pedal, and when it is determined that the vehicle braking state does not correspond to the brake pedal operation brake fluid pressure in the wheel cylinders is increased with a pump. In this way, it is possible to obtain a predetermined braking force corresponding to the brake pedal operation at all times.

Abstract: When a vacuum booster fails, an pressure amplifying mechanism increases a wheel brake pressure. After that, even when it is detected that the vehicle is brought into a stopped state, the state in which an increased brake fluid pressure is applied to wheel cylinders is held. If a condition for terminating control to maintain a stationary state of the vehicle is satisfied, that is, if a predetermined time period has elapsed since when the vehicle stops, the operation of the pressure amplifying mechanism is stopped to reduce the wheel cylinder pressure.
